上海某深基坑工程风险识别与模糊评估
|
摘要
首先采用WBS与故障树法进行风险分析,建立风险清单,在此基础上采用模糊综合评判模型进行风险评估,得出基坑施工风险等级,为后来的风险应对提供参考依据。
To effectively assess the construction risk of a deep foundation pit in Shanghai,the WBS method was brought forward to break down the deep foundation pit,and the risk events of construction of the deep foundation pit were identified by use of the fault tree method.Finally,the construction risk degrees were evaluated and decided in accordance with fuzzy synthetic evaluation model.The results could be used in risk precaution.
