摘要
在隧道施工中,利用衬砌位移的监控量测数据进行衬砌结构的可靠性评价,对新奥法隧道的动态设计有重要的指导作用。从实测位移出发,提出了隧道喷混凝土衬砌结构的功能函数,讨论了衬砌位移、厚度、喷混凝土材料性能的变异性,并对两个实例用Monte-Carlo法进行了可靠度计算,得到了符合实际情况的结果。
In the dynamic design of tunnel constructed with the New Australian Tunnelling Method,it is important to calculate the reliability of the lining structure by in-situ measurement data of displacements. Following the investigation of variability of random variables including lining displacement,thickness of shotcrete and properties of shotcrete material,the performance functions for section failure are put forward. Two case studies are conducted by using Monte-Carlo simulation to check the rationality and correctness of the proposed method.
