【摘要】 随着盾构隧道在软弱土层或城市地下工程的广泛应用,对盾构隧道施工引起的地表沉降研究也取得了丰硕的成果。结合在较大偏压的复杂环境下盾构施工引起的地表沉降实测数据分析,确定了空间偏压对盾构施工引起的地表沉降的影响是不能忽视的。将偏压下实测数据与正常情况下的监测数据进行对比分析,重点分析了偏压对地表沉降特征的影响,为类似工程的决策提供了有意义的参考。更多还原

【Abstract】 With the wide application of shield tunnel in soft soil or underground engineering in city,plenty achievements in research of settlement due to shield tunnel construction have been gained.The article analyzes the settlement caused by shield tunnel construction in various complex surroundings according to monitoring data in-site. It can not be ignored that various altitudes in space influence the settlement caused by shield tunnel construction.According to the project case,monitoring data in various altitudes is compared with the normal monitoring data.It is concluded that the settlement caused by shield tunnel construction in various altitudes has particular modality.Herein, It may be useful reference to similar engineering in future.更多还原
