摘要
根据新奥法原理并结合工程地质条件,采用全断面开挖施工,对隧道施工进行了数值模拟,就其模拟结果进行了详细分析,从而找出隧道施工中围岩及支护结构的应力应变发展变化规律。
Based on the New Austrian Method, the paper carries out the numerical simulation of the tunnel construction by using the lull-section excavation construction combined with the engineering geological conditions, detailedly analyzes the simulation results, to find the change law of the stress-strain of the surrounding rock and the supporting structure in the tunnel construction.
