复杂条件下城市地铁隧道施工地表沉降探讨

Discussion of Surface Settlement in Construction of Urban Metro Tunnel under Complicated Condition

随着现代城市化进程的不断加快,地下交通轨道网在城市交通建设中的比重不断加大。城市地铁隧道的建设必然会打破原来的地下岩土体的平衡状态,从而构建新的平衡,地表沉降将会是地下轨道交通网建设过程中必然面对的问题。针对复杂条件下城市地铁隧道施工地表沉降问题进行探讨,提出较为有效的解决办法。

With the continuously speeding up of modern urbanization process, the proportion of underground traffic rail network is continuously increased in the construction of city traffic. The construction of urban metro tunnel will certainly break the original balanced state of underground rock mass so as to build the new balance. The surface settlement will be the problem inevitably faced in the construction of underground rail traffic network. The article discusses the surface settlement problem in the construction of urban metro tunnel under the complicated condition, and puts forward the more effective solving method.
