摘要
地铁施工会引发地面沉降,若处理不当,会造成严重的生命及财产损失。地铁施工引发的地面沉降可以通过布置地面沉降观测点进行现场监控,但是地面监控点数量的多少及其位置的设定是一个需要认真考虑的问题,以哈尔滨地铁1号线盾构施工区域两侧地面沉降实际观测数据为基础,分析盾构施工区域地面沉降与上覆黑土厚度关系,为今后哈尔滨将要施工的9条规划线路的纵向地面沉降估算提供一条较为合理的途径,同时为更合理地布置地铁施工区域地面沉降观点提供较好的估计方法。
With the development of urban transportation,public land transportation systems are unable to meet people’s requirements of high-quality traffic.Therefore,underground traffic system such as subway has been rapidly developing in many cities in China.Ground settlement caused by subway constructing, however,can result in relatively large economic and life loss if incorrectly treated.The ground surface settlement caused by underground construction can be in-situ monitored at selected monitoring spots,the number and positions of which have to be properly considered.In this paper,based on the monitoring data of the ground surface settlement on both sides of the shield construction area of Harbin metro line 1, statistical relationships of ground surface settlement with respect to the thickness of overlaying black-soil are obtained,which can provide a reference to evaluate the ground surface settlement and to select the monitoring spots during the construction of the planning 9 metro lines in Harbin.
