THE RELIABILITY STUDY ON STABILITY OF BRACING STRUCTURE FOR EXCAVATION
-
摘要: 采用结构可靠度理论研究基坑支护结构的稳定可靠度问题,通过JC法计算实例的稳定可靠指标,得出了在多元失稳模式下基坑支护结构失稳的概率界限范围。Abstract: In this paper, the study on stable reliability of bracing structure for excavation is engaged in by means of structural reliability theory.By using JC method, the concrete examples stable reliability is calculated and the bounds of whole failure probability under multiple instability modes are obtained.
