摘　　要：基坑安全是基坑施工的关键问题,基坑安全的关联因素多种多样,搞清这些关联因素对基坑的影响特征对基坑科学的发展具有重要的现实意义,通过对环太湖流域(笔者称之为太湖软土区)各类基坑事故的调查分析,初步摸清了太湖软土区基坑安全的关联因素以及这些关联因素对基坑的影响特点,提出了确保基坑安全的一些关键技术措施,为太湖软土区基坑工程的科学设计与施工提供了基础依据,介绍了环太湖流域的自然地理特征、地层结构、岩土物理力学性质、水文地质特征和岩溶特征等基本背景资料,给出了工程实例。Safety of foundation pit is key for foundation pit construction. Factors related m foundation pit safety are many and varied. It is very necessary that get m the effects of them in foundation pit construction. According to the investigation and analysis for accidents of foundation pit at the surrounding Taihu lake, these factors related to foundation pit safety and their influences for foundation pit safety are summed up. Some key technological measures to ensure safety in foundation pit construction have been put forward. The investigation conclusions provide scientific basis for foundation pit design and construction. The natttral graphical features, slratum smacmre, physical properties and mechanical properties of rock and soil, hydrogeological features and karst features at the surrounding Taihu lake have been introduced. Some examples for engineering accident have been given.
