深基坑生命周期安全评价体系构建

The deep foundation ditch’s life cycle safety assessment system model construction

基于生命周期理论,建立生命周期安全评价模型,将深基坑工程从前期资料准备,总体规划设计,施工,竣工后这四个阶段划分为四个相对独立的单元。每一个单元都是一个生命周期,对每个单元均进行清单分析,可以由清单分析得出的结论对每一个单元给出对安全指标和经济指标。在此基础上进行最后总分析,对整个工程进行系统评价。

Based on life cycle theory, the article establishes life cycle safety assessment model, and divides the deep foundation ditch project into four relative independent parts, prophase information prepare, general planning design, construction,and completion. Every part is one life cycle, and we can take every part into list analysis, which could get conclusion of safety index and economy index. Base on the four parts list analysis, we can take final bulk analysis, and evaluate the whole project system.
