摘要

研究目的：在地铁施工中使用可靠的监测与信息反馈技术手段能够有效防止事故的发生。采用竖井联系三角形测量,把地上和地下联系起来。加强对变形、收敛、拱顶下沉以及地面沉降的监测,并将各项监测数据及时整理、绘制位移-时间等变化规律曲线,对初期时态曲线进行回归分析,可预测出可能出现的最大变形值、应力值等重要参数,为暗挖风险预控提供了重要依据。

研究结论：应用严密的施工测量与信息反馈技术,时时掌握被监测物的变形情况,进行预测,及时调整设计和施工参数,为地铁施工提供了准确的依据,对地铁建设和同类地铁施工环境具有重要借鉴和参考价值。

Abstract

Research purposes：In metro construction, using the reliable monitoring and information feedback technologies can prevent the appearance of accidents. Application of the triangle surveying in shaft can connect the ground with the underground. To strengthen monitoring the deformation, convergence, the vault settlement and ground settlement along with sorting out the monitored data, mapping the displacement-time change curves in time and making regression analysis of the state curves in early stage can predict the important parameters that probably appear, such as the max. deformation value and max. stress value so as to provide the important basis for controlling the risk in advance to the metro construction with subsurface excavation method.

Research conclusions：Application of engineering measurement technology and information feedback technology can know the deformation situation of the monitored objects and therefore can make prediction and adjust the design and construction parameters in time for providing the accurate data to the metro construction and the reference to the similar works.
