Available in PDF, EPUB and Kindle. Book excerpt: An essential aspect of investigations of settlement of foundations and of stability of structures and earthworks is the experimental determination of the stress-strain-time responses and strength properties of clay and organic soils. These should not only be representative of the conditions that control and have significant direct applications to the solutions of the practical problems involved but also should be reliable and fully adequate for the purposes of these investigations. It should be recognized that clay and organic soils exhibit significant creep in their performances at ordinary working stress levels. The prerequisite to the attainment of these very practical engineering objectives are: first, to test and treat real soils under the influences of essentially real and representative conditions that control, and; second, to work consistently toward high conceptions of adequacy and standards of excellence in soil investigations.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this research is the development of a new constitutive model to describe the behavior of cohesive soils under time dependent loading. In the work presented here, the modified SIMPLE DSS model is expanded to account for the effects of strain rate on clays in simple shear conditions. The response of clay soils is highly dependent on the rate of strain for both effective stress path and stress-strain behavior. The undrained shear strength is strongly influenced by strain rate both in monotonic and cyclic simple shear tests. Nevertheless, the few available experimental results cover a very limited range of loading conditions and rates. The existing literature established that the soil response display a unique relationship between shear strength and log scale of strain rate. To include the effects of strain rate, the modified simple effective stress model starts with two assumptions: (1) a specific shear strength corresponds to a specific strain rate in a unique relation; and (2) the effect of strain rate does not change the failure envelope. The proposed model is developed from the original SIMPLE DSS model, based on an effective stress formulation in a reduced stress space, and utilizing concepts related to the framework of bounding surface plasticity. The proposed model evaluation was carried out comparing model simulations with results of simple shear tests on Boston Blue Clay and San Francisco Young Bay Mud. The model capability is useful especially in strain rate dependent responses for both monotonic and cyclic behavior, including irregular loading and step-changed condition. It was found that undrained shear strength in simple shear is directly related to strain rate effects and the responses in cyclic test show the more rate dependent behavior than those in monotonic test. The proposed model is able to predict the increase in undrained shear strength for higher strain rate.

This book was released on 1961 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigations were made of the effect of strain rate on the stress vs. strain behavior of two saturated soils. Included are: (a The results and analysis of a series of static triaxial compression tests on a saturated Loess, (b) The results and analysis of a series of rapid triaxial compression tests on a saturated Loess, and (c) The results and analysis of a series of rapid triaxial compression tests on a saturated clay. The static triaxial tests were important in consistently and fully describing the patterns of behavior of the soil during very slowly applied stresses and served as prerequisites to the rapid triaxial tests. The tests performed at rapid rates of strain were of a preliminary nature and the conclusions drawn are to be used in planning a compreh nsive program investigating the effects of strain rate on the stress- strain behavior of saturated soil.
