盾构隧道施工引起地表及周边建筑物沉降分析

Analysis on Ground and Surrounding Buildings Settlement Induced by Shield Tunneling

文章应用非线弹性及线弹性本构模型,对长春地铁1号线火车站站—北京大街站区间双线隧道盾构施工中,在不同施工工序条件下地表沉降及周边建筑物沉降进行分析,得到了使得地表沉降及建筑物不均匀沉降最小的最佳工序,以期为长春地铁工程盾构施工、地表沉降及建筑物不均匀沉降控制提供参考。

The paper uses the model for non-linear elastic and linear elastic constitutive members, discuses the shield tunneling construction of Railway Station — Beijing Street Station section of Changchun metro line 1. It makes analysis on the ground surface settlement and surrounding building settlement under different conditions of construction process, has worked out the best process for controlling surface and building uneven settlement to the minimum extent of settlement in order to provide a reference for Changchun metro shield construction, control of uneven surface subsidence and sedimentation of structures.
