复杂地层特大断面车站拱盖法施工监测数据分析与应用

Monitoring Data Analysis and Application of Arch Cover Method in Construction of Station with Large Section in Complex Strata

复杂地层特大断面车站拱盖法施工工序转换频繁,受力体系转换多,安全隐患极大。论文以贵阳某采用拱盖法施工的地铁暗挖车站施工项目为例,对车站工程现场进行监测,对沉降、净空收敛等进行分析,并利用监测数据动态调整设计方案,实现信息化施工管理。

The construction procedure of arch cover method of station with large section in complex stratum is frequently changed,and the stress system is frequently changed,which leads to great safety risks.Taking the construction project of underground subway station constructed by arch cover method in Guiyang as an example,the paper monitors the station engineering site,analyzes the settlement,clearance convergence,and uses the monitoring data to dynamically adjust the design,and realizes the information construction management.
