摘　　要：结合济南市某电力隧道,采用有限元软件MIDAS GTS模拟隧道开挖对周边环境的影响分析,并通过实际工程验证了超前小导管+钢拱架的支护体系在浅埋暗挖隧道中的适用性。另外,针对碎石特殊地层所面临的问题提出解决措施,为济南地区其他浅埋暗挖隧道工程提供有益的参考。Combined with a power tunnel in Jinan,the finite element software MIDAS GTS is used to simulate the impact analysis of tunnel excavation on the surrounding environment,and the actual project verifies the applicability of the supporting system of the leading small pipe+steel arch in the shallow buried tunnel. In addition,the solutions to the problems faced by the gravel special stratum are proposed,which provides a useful reference for other shallow buried tunnel projects in Jinan area.
