以黄衢高速公路小净距隧道为工程依托,运用有限元的基本理论,采用ABAQUS软件对小净距隧道围岩强度、爆破振动速度及对结构影响的关系进行研究。研究结论对科学应用小净距隧道,克服隧道洞口狭窄地形,避免大开大挖,减少公路用地,保护公路沿线绿色生态有着重要意义。 Based on the project of small clear distance tunnel of Huangqu Highway, the relationship between strength of surrounding rock and blasting vibration velocity and its influence on structure with small clear distance tunnel is studied by using the basic theory of finite element and ABAQUS software. The conclusion of the study is that it is of great significance to apply small-distance tunnels to science, overcome the narrow terrain of tunnel openings, avoid digging openly and dug, reduce road land use and protect green ecology along the highway.
