摘要
在山区隧道修建过程中,岩溶是主要的地质灾害之一。当前有关于岩溶隧道工程的论文,主要针对具体工程实例进行具体分体,所得结果的普适性有所限制。本文以千岛湖引水隧道工程为背景,采用Abaqus模拟隧道周围不同位置存在隐伏溶洞时的状况,得出了隐伏溶洞对隧道位移、应力以及塑性区范围的影响,为岩溶隧道的设计和施工提拱了一定的指导。
Karst is one of the main geological disasters during the construction of tunnel.The existing paper about karst tunnel projects are mainly divided into specific engineering cases,and the universality of the results is limited.This paper takes Qiandaohu tunnel project as the background,arrive at a conclusion about the influence of karst tunnel displacement,stress and plastic zone through simulate different cave positions around the tunnel.It provides guidance for the design and construction of karst tunnel.
