地基基础工程标准化与概率极限状态设计原则

Stadardization of Foundation Engineering and Probabilistic Limit State Design Approach

90年代地基基础工程标准化工作面临如何贯彻概率极限状态设计原则的问题。本文回顾了80年代我国地基基础领域中可靠性研究的进展;分析了地基基础概率极限状态设计不同于上部结构的四个主要特点;对于将结构工程设计可靠性分析方法引入地基设计时必须考虑的基本概念,提出了五个值得注意的问题;并对今后工作提出了若干建议。本义是在中国工程建设标准化协会地基基础委员会成立大会暨地基基础标准技术讨论会上的专题报告。

Foundation engineering standardization based on the probabilistic limit state design approach will be carried out in the nineties. In this paper, the advance on the reliability research in foundation engineering field has been summarized. Main differences between superstructure and foundation in reliability design have been distinguished and some fundamental concepts for leading the structure reliability emalysis method into the foundation design have to be noted. At last, suggestions have been made for foundation engineering standardization.
