溶洞对贵阳轨道交通工程隧道影响的数值分析
Numerical Simulation of the Influence of Cave on Guiyang Railway Tunnel
摘要
Abstract
With the continuous development of infrastructure in southwest mountainous area of China, the karst disaster of karst tunnels has become a key technical problem of engineering survey, design and construction.In this paper, finite element software ABAQUS is used to analyze the stability of surrounding rock in the subway construction of Guiyang Metro, and the tunnel structure and surrounding rock stability in tunnel excavation are studied.The stress characteristics of tunnel structure during tunnel excavation and the displacement of tunnel surrounding rock during tunnel excavation are analyzed.The influence of cave location, cave size and different clearance distance between cave and tunnel on the stability of surrounding rock in metro construction are discussed.The research results have been used in the construction of practical projects, and have reference value for other similar areas of shield tunnel construction.关键词
