膨胀岩土地层的地铁基坑施工监测技术

Expansion of the subway foundation pit construction monitoring technology of rock and soil formation

以成都地铁2号线东延线龙泉车站基坑施工为例,针对工程的地质情况,对工程施工中的截排水措施进行了探讨,研究了膨胀土地层信息化施工监测技术的目的和监测项目,并对监测数据作了分析,得出了相关的结论。

Taking east widening line Longquan station foundation construction of Chengdu subway No. 2 railway line as an example,in light of the engineering geology conditions,the paper explores the section drainage measures in the project construction,studies expansive soil stratum infor-mation construction monitoring technology targets and monitoring projects,and analyzes monitoring data,and finally draws relevant conclusions.
