Based on the Reliability of Composite Pile Foundation Design Theory Research

Abstract:

Due to the physical properties of the soil between piles discrete，thus，composite pile foundation 's bearing capacity exists some uncertainty. So far, the study of the reliability of composite pile foundation is transform from the allowable stress method to the probability limit state design method. That is to say probability definite value design method. Therefor , determine the resistance subentry coefficient become the key of the design method. This paper introduces the significance of the subentry coefficient and the subentry coefficient of the composite pile foundation. Through the calculation of engineering examples, this article give the values of the subentry coefficient and provide a reference for the design of composite pile later.
