摘 要:在考虑施工动态变化和人为差错失效模式的基础上,构建基坑工程施工风险的概率估算、面向过程的动态风险分析和控制体系,提出将专家调查法和模糊综合评判法相结合,对基坑工程各工序施工人为差错进行动态风险分析。结合土钉墙支护基坑工程,应用建立的动态风险分析体系,对失效概率较大的施工工序进行风险分析,提出施工动态管理的相应控制措施。结果表明,在缺乏人为差错资料数据库的情况下,提出的风险动态分析控制体系对于考虑人为差错的工程风险动态分析有其实用价值。In view of the dynamic characteristics of construction and human errors, the risk probability estimation system and the process-oriented dynamic risk analysis and control system for the excavation engineering was constructed. And it was suggested that the results from experts" investigation method and fuzzy synthetic assessment method should be combined to analyze the risk of the working procedures in the excavation engineering due to human errors. Based on an engineering of soil-nailing supported foundation pit, the proposed framework was applied to analyze the working procedures with bigger invalidation probability and corresponding control measures were put forward. It shows that the risk analysis system is of practical value in the absence of human errors database.
