大型地下洞室施工过程中的可靠性分析

通过对Monte-Carlo随机有限元和系统可靠度计算的? 分支法的研究分析，考虑把二者联合起来分析洞室施工过程安全性，提出了一种大型地下洞室开挖过程中可靠度评价的方法。以海南工程为例，对地下洞室开挖过程中的每一步进行可靠性评价，分析比较了多层耦合法与分层逆作法之间洞室施工过程中的稳定性，比较了二者的优缺点。从而对多层耦合法施工有一个全面的了解和比较，为今后的大型洞室快速施工提供科学依据。

Reliability analysis of large underground caverns in construction

Through analyzing the Monte Carlo random finite element and the system reliability method of βembranchment method, we consider to combine the two theories, and then a reliability analysis method is proposed to use in the process of underground caverns excavation. The method for evaluating the big cavern reliability in construction has researched. Taking the Hainan project for example, we analyze the every excavation step, and compare the two methods’ shortcomings and merits. So we can get a full knowledge about the several layers excavating method so as to provide reference for the fast excavating.
