摘要
目前在基坑支护结构设计中采用的安全系数法,并不能明确地评定基坑支护结构的安全度,引入可靠度理论成为一种必然趋势。文章对基坑支护结构内力进行了β分布拟合,基于可靠度理论得出了结构内力的推荐值,并与常规设计计算值进行了比较,为基坑支护结构采用可靠度理论进行设计提供了一种分析方法。
Safety factor which is used to design braced structures for deep excavation, can not give us a realizing safety, so we should apply reliability theory in deep excavation engineering. The paper studies β distribution function of intemal forces, works out rational internal forces based on reliability theory, and compares these numerical values to conventionality design, so it points out another approach to design braced structure for deep excavation in reliability theory.
