Download or read book Analysis of The Factors in Earth Pressure and Deformation of Buried Flexible Pipes Through Centrifuge Model Tests written by L. Li and published by . This book was released on 1994 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of centrifuge model tests was conducted to estimate parametrically effects of the following factors on earth pressure and deformation of buried flexible pipes: pipe flexibility, pipe installation type, ground condition, and three burial dimensions (cover height, ditch width and bedding thickness). The tests yielded accurate measured data of circumferential distributions of normal and tangential earth pressures on the model pipes, circumferential distributions of bending strains in the pipe wall, and vertical pipe deflection, fully quantifying the effects of the investigated factors. It was found that Japanese current design standards, based on Marston-Spangler theory, do not conform to the test results by ignoring the effects of almost all the factors on the earth pressures, and, as a result, they specify definitely unsafe design values of bending moment and pipe deflection for the case when the pipes are buried by the open excavation method using sheet-piling.

Book excerpt: Physical Modelling in Geotechnics collects more than 1500 pages of peer-reviewed papers written by researchers from over 30 countries, and presented at the 9th International Conference on Physical Modelling in Geotechnics 2018 (City, University of London, UK 17-20 July 2018). The ICPMG series has grown such that two volumes of proceedings were required to publish all contributions. The books represent a substantial body of work in four years. Physical Modelling in Geotechnics contains 230 papers, including eight keynote and themed lectures representing the state-of-the-art in physical modelling research in aspects as diverse as fundamental modelling including sensors, imaging, modelling techniques and scaling, onshore and offshore foundations, dams and embankments, retaining walls and deep excavations, ground improvement and environmental engineering, tunnels and geohazards including significant contributions in the area of seismic engineering. ISSMGE TC104 have identified areas for special attention including education in physical modelling and the promotion of physical modelling to industry. With this in mind there is a special themed paper on education, focusing on both undergraduate and postgraduate teaching as well as practicing geotechnical engineers. Physical modelling has entered a new era with the advent of exciting work on real time interfaces between physical and numerical modelling and the growth of facilities and expertise that enable development of so called ‘megafuges’ of 1000gtonne capacity or more; capable of modelling the largest and most complex of geotechnical challenges. Physical Modelling in Geotechnics will be of interest to professionals, engineers and academics interested or involved in geotechnics, geotechnical engineering and related areas. The 9th International Conference on Physical Modelling in Geotechnics was organised by the Multi Scale Geotechnical Engineering Research Centre at City, University of London under the auspices of Technical Committee 104 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). City, University of London, are pleased to host the prestigious international conference for the first time having initiated and hosted the first regional conference, Eurofuge, ten years ago in 2008. Quadrennial regional conferences in both Europe and Asia are now well established events giving doctoral researchers, in particular, the opportunity to attend an international conference in this rapidly evolving specialist area. This is volume 1 of a 2-volume set.

Download or read book Centrifuge Modeling of Oblique Pipe soil Interaction in Dense and Loose Sand written by Pijush Debnath and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to relative ground movement, buried pipelines experience geotechnical loads. The imposed geotechnical loads may initiate pipeline deformations that affect system serviceability and integrity. Engineering guidelines (e.g., ALA, 2005; Honegger and Nyman, 2001) provide the technical framework to develop idealized structural models to analyze pipe-soil interaction events and assess pipe mechanical response. The soil behavior is modeled using discrete springs that represent the geotechnical loads per unit pipe length developed during the interaction event. Soil forces are defined along three orthogonal directions (i.e., axial, lateral and vertical) to analyze the response of pipelines. Nonlinear load-displacement relationships of soil defined by a spring, is independent of neighboring spring elements. However, recent experimental and numerical studies demonstrate significant coupling effects during oblique (i.e., not along one of the orthogonal axes) pipe-soil interaction events. In the present study, physical modeling using a geotechnical centrifuge was conducted to improve the current understanding of soil load coupling effects of buried pipes in loose and dense sand. A section of pipeline, at shallow burial depth, was translated through the soil at different oblique angles in the axial-lateral plane. The force exerted by the soil on pipe is critically examined to assess the significance of load coupling effects and establish a yield envelope. The displacements required to soil yield force are also examined to assess potential coupling in mobilization distance. A set of laboratory tests were conducted on the sand used for centrifuge modeling to find the stress-strain behavior of sand, which was used to examine the possible mechanisms of centrifuge model test. The yield envelope, deformation patterns, and interpreted failure mechanisms obtained from centrifuge modeling are compared with other physical modeling and numerical simulations available in the literature.

Download or read book Theory and Application of Hydraulic Modeling written by Taro Arikawa and published by CRC Press. This book was released on 2024-04-17 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume from Japan’s Research Subcommittee on Methodology for Dealing with Geomaterials in Hydraulic Model Experiments presents readers with a state-of-the-art overview of experimental and computational methods used to address similarity scaling incompatibilities present in fluid–sediment flows. Readers will gain an understanding of complex phenomena in the boundary fields of hydraulics and geotechnical engineering. Chapter contributors focus on the phenomena that are affected by the interactions between fluid wave and ground in a complex field, which for many years have been challenging to process and model. In addition to describing the implementation of model tests and the concept of the law of similarity, this book contrasts these phenomena with the laws of similarity, describes models and numeral analysis methods, and explains important considerations using experimental case studies. Each chapter is written by leading researchers in Japan who are members of the Research Subcommittee on Methodology for Dealing with Geomaterials in Hydraulic Model Experiments. The chapters are closely linked but are written so that each can be read individually. Readers will be able to apply this knowledge to their work and to create models that more accurately simulate the interactions between wave and ground, allowing them to better understand these phenomena and devise more appropriate strategies for defense and so on when necessary. This collection provides information that can be used by young researchers and post-graduate students in the boundary fields of hydraulics and geotechnical engineering who aim at becoming civil engineers, and it will be of particular value to practicing engineers of all experience levels who must regularly analyze complex interactions between fluids and ground.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes one phase of the research on the modeling of buried structures by centrifuge testing and by numerical methods. Testing in the centrifuge makes it possible to simulate the gravity-induced overburden pressure effects that dictate the soil stiffness which in turn determine the soil-structure phenomena. Scaled model testing in the centrifuge is used in the project to validate analytical methods commonly used to analyze soil-structure interaction problems. Data obtained by testing a 4-in diam. pipe at 50 g under a static surface pressure loading consist of radial deflections and strains measured around the pipe. These experiments were analyzed by a finite element program in which different constitutive models were incorporated, including a non-linear elastic model and an elasto-plastic model. On the basis of comparison with centrifuge test data, the suitability and accuracy of the different analyses were assessed.
