摘      要：The excavation for the municipal tunnel will disturb the soil around the tunnel,and the deformation and subsidence of the earth surface always take place,which may lead to instability and even collapse for the building above the tunnel. At the same time the deformation and subsidence of the earth surface affect the normal use of underground municipal pipelines,and may cause the road sudden collapse,leading to significantly traffic accidents. The authors did a research by simulating for the excavation of municipal tunnel and designed the related supporting plan,and put forward some suggestions and measures for the design and construction of urban tunnel.
