Bayesian Statistic

In static load test, most of piles do not destroy, the piles still exist capacity, which reduce the reliability index of pile foundation. This paper employs Bayesian Statistic method to update the measured capacity of piles. Meanwhile, based on updating data, the reliability index is calculated considering the destruction of piles. The case study shows that the reliability index of capacity becomes large when the time of pile destruction increases. Therefore, when judging the safety of pile foundation, it is highly necessary to consider the influence of pile destruction on reliability of piles.

Pile Testing

The application of pile foundation is promoted by the rapid development of the high speed railway, highway, high-rise buildings and big volume weight of building. However, the static load test and low strain test play a very important role in pile foundation inspection and ensurement of the quality of pile foundation engineering. In this paper, combined with the engineering of the basis of a hospital in lanhou, the author analyzed the results of 7 test piles static load test and a large number of low strain test and summarised pile testing contents and methods. At the same time,the bearing capacity of anchor pile in static load test is discussed.

Contrast Analysis

Firstly, the technology of screw pile is introduced briefly. It has high body quality, high bearing capacity and wide application prospect. Then, based on engineering examples, the results of static load test and high strain testing for the bearing capacity of SCREW PILE foundation are analyzed contrastively. The bearing capacity value tested by high strain dynamic testing is higher than the static loading test’s with 13%~21%, which should be attached importance in the check and accept and application of the screwed pile. The analysis and sum up of testing results should be considered to the design and application of screwed pile, providing some reference to the quality judge and bearing capacity confirming is another purpose in the paper.

Abstract The article deals with numerical analyses of a Continuous Flight Auger (CFA) pile. The analyses include a comparison of calculated and measured load-settlement curves as well as a comparison of the load distribution over a pile's length. The numerical analyses were executed using two types of software, i.e., Ansys and Plaxis, which are based on FEM calculations. Both types of software are different from each other in the way they create numerical models, model the interface between the pile and soil, and use constitutive material models. The analyses have been prepared in the form of a parametric study, where the method of modelling the interface and the material models of the soil are compared and analysed. Our analyses show that both types of software permit the modelling of pile foundations. The Plaxis software uses advanced material models as well as the modelling of the impact of groundwater or overconsolidation. The load-settlement curve calculated using Plaxis is equal to the results of a static load test with a more than 95 % degree of accuracy. In comparison, the load-settlement curve calculated using Ansys allows for the obtaining of only an approximate estimate, but the software allows for the common modelling of large structure systems together with a foundation system.
