黑龙江哈尔滨地铁盾构法施工地面变形规律分析

摘要

In order to study the Harbin subway shield law construction stratum distortion rule;Through the scene reconnaissance,the collection and entire should the project geological data,the construction craft,conducts the research to the stratum distortion rule,based on this analyzed summarizes the rule which the Harbin area subway shield construction stratum distorted,the findings had indicated that in the shield construction process,the surface and the underground different depth＇s stratum each direction＇s distortion value was various,along with increased with the tunnel middle line distance reduces,the surface subsidence value was smallest,provided for the similar project has borrowed the bamboo slip.%为研究哈尔滨地铁盾构法施工地层变形规律。通过现场勘察,监测及整理该工程的地质资料、施工工艺、地层变形监测数据,对地层变形规律进行研究。在此基础上分析总结了哈尔滨地区地铁盾构施工地层变形的规律,地表及地下不同深度的地层各个方向的变形值各不相同,随着与隧道中心线距离的增大而减小,地表处沉降值最小,为类似工程提供了借签。
