ANALYSIS ON BEARING CAPACITY RELIABILITY STATISTICS OF STATIC PRESSURE PILE IN XI'AN

摘要

Considering the matching with the upper structure design and geotechnical engineering requirements of its development and trend,to evaluate its safety using reliability method is the focus of research of reliability theory in pile foundation engineering.It has broad application prospects.Using the center point method,The paper derived The calculation formula of the bearing capacity of pile foundation reliability index.Though collecting 100 groups bearing capacity test data of static pressure pile from 27 sites,Considering three kinds of basic load combination,the paper calculated and analyzed the reliability index of bearing capacity of static pressure pile in Xi'an.
