摘要
以某高速公路双连拱隧道为工程背景,采用FLAC3D数值模拟软件对三导洞开挖工法施工中隧道围岩的力学响应特征进行计算与分析,理清位移场与应力场的变化趋势,旨在为后续的监测与支护提供指导。
Based on a double-arch tunnels for expressway,the mechanical response of the tunnel surrounding rock with 3-heading excavation method is calculated and analyzed by FLAC3D.The changing trend of stress field and displacement field is researched to give a guide for the project monitoring and supporting.
