灯草塘隧道施工监控量测及分析

隧道施工监测直接关系到工程质量与安全,是信息化施工的一项重要课题,越来越受到施工单位与业主的重视。在灯草塘双连拱隧道中,对隧道围岩变形及地表沉降进行了现场监测与分析研究,获得了隧道各施工阶段的地表沉降、拱顶下沉和周边收敛数据资料,有效地控制了隧道围岩变形,成功地对隧道的地质灾害进行了动态预测、预报,避免了重大事故的进一步发展。研究成果对类似工程具有一定的指导意义和实际应用价值。

Monitoring and Analysis of the Construction of Dengcaotang Tunnel

The tunnel construction monitor,an important subject in informational construction,is directly related to the project quality and security,so it receives more and more attention from the construction units and the owners.In the process of the construction of Dengcaotang double-arch tunnel,insitu monitoring and analyses were carried out for the deformation of the surrounding rock and the ground settlements.Ground settlements,vault subsidence and the horizontal convergences during each period of construction were obtained to control effectively the surrounding rock deformation.At the same time the geological hazards were predicted and forecasted successfully The research results provide guidance to similar tunnel engineering projects.
