基于事故树分析的基坑施工安全评价研究

针对基坑施工这项复杂的系统工程，应用事故树建立边坡应急治理方案选择的层次结构模型，将复杂问题进行处理，结合经济、技术和环境等各方面因素，对基坑施工方案进行客观、科学的评价，最后以工程特点和评价结果为基础，为基坑支护过程制定施工安全专项方案，在管理、检查、消防、应急等方面提出安全保障措施。

Safety Evaluation of Foundation Pit Construction Based on Fault Tree Analysis

Based on the complex system project of foundation pit construction, the fault tree analysis was applied to establish the hierarchical structure model selected by the slope emergency treatment scheme to treat complex problems. And then the construction scheme of foundation pit supporting is evaluated objectively and scientifically by taking account of economy, technology and environment. Finally, special construction scheme for the foundation pit supporting process is formulated and safety precautions on management, inspection, firefighting and emergency, etc. are put forward based on the engineering characteristics and the evaluation results.
