Available in PDF, EPUB and Kindle. Book excerpt: This theses will evaluate the accuracy of the electrical and mechanical cone penetration test for predicting pile capacity when compared to observed pile capacity results from nearby pile load tests. The research was accomplished by finding former construction sites which had pile load test, electrical cone penetration test, mechanical cone penetration test, and boring log data all located within a close proximity of one another. Pile capacities were predicted using the electrical and mechanical cone penetration test sounding data. Then the predicted pile capacities were compared to the observed pile capacity determined by nearby pile load tests. As a natural consequence of performing the latter analysis, comparisons could also be made between the results of electrical and mechanical cone penetration tests at a given site. Soil layer divisions along with the average friction ratio and end bearing resistance measurements in each layer were identified and compared from electrical and mechanical cone penetration test sounding data. Computer programs, designated MCPTUFR and PLAID, were developed to predict pile capacity using conventional methods from mechanical and electrical cone penetration tests respectively. Theses. (jhd).

Available in PDF, EPUB and Kindle. Book excerpt: This study presents an evaluation of the performance of eight cone penetration test (CPT) methods in predicting the ultimate load carrying capacity of square precast prestressed concrete (PPC) piles driven into Louisiana soils. Sixty piles were identified, collected, and analyzed. The following methods were used to predict the load carrying capacity of the collected piles using the CPT data: Schmertmann, Bustamante and Gianeselli (LCPC/LCP), de Ruiter and Beringen, Tumay and Fakhroo, Price and Wardle, Philipponnat, Aoki and De Alencar, and the penpile method. The ultimate load carrying capacity for each pile was also predicted using the static method, which is used by the Louisiana Department of Transportation and Development for pile design and analysis.

Available in PDF, EPUB and Kindle. Book excerpt: Cone penetration testing (CPT) is a well established geotechnical subsurface investigation technique commonly used for site characterization and soil classification. The CPT gives real time end resistance, side friction, and pore pressure readings. Axially loaded piles also share these two resistance mechanisms, suggesting the cone can be considered similar to a miniature pile. This study focused on evaluating eight CPT methods prediction of pile bearing capacity. The Nebraska Department of Roads (NDOR) conducts dynamic load tests (PDA) of driven pile to verify pile capacity for bridge foundations. 91 comparisons of CPT logs and PDA data were evaluated. CPT prediction methods were assessed based on prediction ratio and statistical performance. Controlling bearing mechanism was identified as a key influence in method accuracy. Subsequently, piles were identified as end bearing or skin friction pile for further method analysis. The CPT methods were calibrated to maximize accuracy for Nebraska's regional soil conditions. A numeric modeling study was also conducted to investigate cone vs. pile behavior. The study found cone influence depth for end resistance about 10D, while pile influence depth ranged from 1-3 times the diameter. Relative sensitivity to over and underlying soft/hard layers was also identified. Most importantly, computational modeling confirmed qb/qc factors in accordance with or slightly higher than the empirical methods. Bearing capacity was most accurately predicted by modified Prince & Wardle method for end bearing pile, while a modified Philipponnat's method gave the best prediction for friction pile. CPT based pile design developed by the study offers a more robust design approach to accompany modern soil investigation techniques.

Book excerpt: Prior to performing twenty-eight axial and two lateral load tests on piles at Mississippi the Lock and Dam 26 project, an in situ test program was conducted. The program consisted of four cone penetration tests, twelve pressuremeter test borings, and four standard penetration test borings. Comparisons of pile capacity predictions were made for each of the in situ test methods. The initial study generated four reports and voluminous test data. This is a summary of those reports. (fr).

Download or read book Determination of P y Curves by Direct Use of Cone Penetration Test CPT Data written by SHAWN SHAHRIAR ARIANNIA and published by . This book was released on 2015 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current best practice in geotechnical engineering in determining lateral capacity of piles is to replace the soil reaction with a series of independent springs. Basically, the model uses beam theory to represent the pile and uncoupled, non-linear load transfer functions, called p-y curves to represent the soil. Most of the existing methods for determining p-y curves are highly empirical, based on a limited number of cases of laterally loaded piles, which were instrumented, enabling to measure the pile deflection in discrete depth intervals subject to different lateral load (i.e. Matlock 1970, Reese 1975). In essence, these methods have their own limitations, and are mainly applicable for the conditions similar to the tested conditions. Although later, more detailed investigations by different people addressed some of the problems, still the basis of the existing design programs such as LPILE, or procedures introduced in applicable codes such as API (American Petroleum Institute), is the same original recommendations made by Matlock and Reese during seventies. In recent era, demand in employment of in-situ direct-pushed based methods using multi-measurement in-situ devices, such as the seismic cone penetration test with pore water measurement (SCPTu) and Seismic Flat Dilatometer Test (SDMT) is significantly increased. The main objective of this research is to introduce a unified CPT-based approach for determining p-y curves and pile responses to lateral loads. The suggested approach will provide explicit and defined steps/criteria to develop p-y curves for piles subjected to lateral loads using CPT data. CPT data will be used to determine soil strength parameters. Recent developments in relating CPT data to soil basic parameters using Critical State Soil Mechanics (CSSM) framework will be implemented in the suggested model. In all current common models, pre-determination of the soil behavior and the model to be used (e.g. Matlock clay, 1970 or Reese sand, 1975), will become warranted even before commencement of the analysis. On the contrary, in the proposed model, the need for the said pre-determination of soil behavior is eliminated. As discussed in Section 2.3.5, soil behavior in the model is being classified into four broad and general groups: drained-dilative, drained- contractive, undrained-dilative and undrained-contractive The main factor driving the suggested analytical approach is Soil Behavior Type Index, Ic. In the proposed approach, the SBT index, Ic, will be used to determine the in-situ characteristics and behavior of the soil. Based on the value of Ic calculated from CPT data, it could be determined that the soil behaves as a sand-like or a clay-like soil, and during the shearing would behave in undrained or drained condition. The measured shear wave velocity during field test using seismic cone penetration test or other methods such as SASW (Spectral Analysis of Surface Waves) or Cross-Hole logging, may be used to determine the small strain shear modulus, G0, which corresponds to the initial stiffness of the linear part of the p-y curve. In this research, the proposed model will be verified using collected case histories of laterally loaded piles with available CPT data at the same site. The p-y curves, and pile force-head displacements determined from the model will be compared to the field-resulted p-y curves and pile head displacement measurements available from the case histories.
