摘　　要：本文通过南京几个深基坑支护结构重大事故的分析,认为深基坑支护是复杂的技术问题,涉及地质、水文、场地环境、设计方案、计算参数及施工方案等方面。其中水是最重要的因素,相应提出处理地基水的具体措施。从几个工程失效原因及分析可看出,只要做到因地制宜,制定合理的支护方案,并认真组织,认真施工,支护失效是完全可以避免的。Basing upon an analysis of heavy losses in deep foundation pit sheet pile wall bracig at Nanjing construction projects, it has been discovered that sort of failures is rather a complicated technical problem closely intertwined with various factors such as geology, hydrology, environmental site condition, projects' design and planning and calculation's parameter, as well as construction method etc, of which and above all, water attributes to the topmost influential factor. Thus. there has been eventually introduced a practicalmethod for water treatment. Basing upon the study of aforementioned analysis, these heavy losses can all be avoided and a complete project can be achieved, on conditions that suitable measures to local condition are well made, a good design of wall bracing is provided, and a strict organization and an efficient management of construction is ensured.
