失败学是在管理学科中孕育并分化出的一个分支学科,近年来开始受到人们的关注。本文依据失败学原理,运用失败树分析法,对某建设项目深基坑支护工程失败原因进行了分析,给出了失败树的逻辑图形,把失败路径、失败过程、主要风险因素及风险控制条件清晰地表达出来,进而对工程项目施工进行安全预警。失败树分析法在对工程项目安全管理、企业经营风险分析和社会危机管理方面有着良好的应用前景。

Failure science is a new branch in management idea. Because the deep pit project failure is normally in practice and the soil is more complex than the upper structure, the failure science is suitable to it. By dint of many failing projects, the failure knowledge becomes scientific technological information, and factors of risk cause can be studied. Then the place and roles of probably failure and risk cause factors are determined. So the failure can be avoided. For any failure projects, there must be some reasons of management. In this paper, a case is studied by failure cause tree analyzing method. For engineering failure which has taken place, while the path, causes and condition of the failure are comparatively certain, the structure of failure tree is comparatively determinate and perspicuous. By analyzing the process of failure, the reasons of failure are clear. Because there are many kinds of project failure in practice, the different failure type can be used by different failure cause tree analyzing logical figure.
