Abstract��
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 nor- mal 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�� |
