Reliability Analysis of Vertical Bearing Capacity of Pile Based on Static Load Tests

Abstract:

Based on the sample range theory in Mathematical Statistics, the general standard variance of vertical capacity of single piles is evaluated according to the data from static load tests, and a method is presented to evaluate the reliability of vertical bearing capacity of pile, of which distribution obeys normal distribution. Finally, results from the case study indicate that it is effective to evaluate the reliability using the method presented in this paper, and the number of tested piles specified in Technical Code for Testing of Building Foundation piles and determining sample range can be interpreted reasonably in theory. Meanwhile, it can give good references to designers to determine the design parameters according to testing piles.
