Study on System Reliability Analysis Method for Composite Foundation Improved by Combined Piles

Abstract:

Based on bearing capacity and settlement control design methods for composite foundation improved by combined piles,as well as the system reliability analysis theory,the system of reliability analysis for composite foundation can be divided into three sub-systems;that are bearing capacity sub-system,settlement sub-system and differential settlement sub-system.The system probability of failure for composite foundation call be obtained by calculating that of three sub-systems respectively.It provides a method of system reliability analysis for composite foundations improved by combined piles.
