搅拌桩防渗墙法的事故树分析

Fault Tree Analysis of Mixing Pile Impermeable Wall

针对堤防工程中搅拌桩防渗墙失效这一事故现象,引入了事故树分析法进行研究,为确定防渗墙的安全提供了可靠依据。同时,介绍了模糊事故树法应用于搅拌桩防渗墙失效概率分析的基本方法,提出了其施工质量控制的一些方法。

Aiming at the failure of mixing pile Impermeable Wall in the dike project, the fault tree analytic method was be introduced and used in the research. It has provided the reliable basis for the determination of cut-off wall＇s security. At the same time, the basic method of how fuzzy fault tree applies in the failure probability analysis of Mixing Pile Impermeable Wall was introduced, and some methods of its construction quality control was proposed.
