摘要
通过对厦蓉线广以隧道左线进口边仰坡在隧道施工过程中变形稳定性变化的分析,结合对拱顶下沉、周边收敛变形和地表位移的监测分析,及时提出了边仰坡异常变形预警,并结合隧道开挖、地质情况、降雨以及加固处理等因素,对监测成果和变形原因进行了分析,提出了有效的险情控制措施,使隧道边仰坡稳定性得到控制,确保了工程安全。
Based on the deformation stability analysis of side upward slope in the left tunnel entrance of Guangyi tunnel in Xiamen-Chengdu expressway,pre-warning of abnormal deformation is presented in time combining with the monitoring of vault settlement,surrounding convergency deformation and surface displacement.The causes of deformation and monitoring results are analyzed combined with tunnel excavation,geological condition,rainfall and reinforcement treatment,etc.Furthermore,control measures are proposed which make the side upward slope stability be controlled to ensure the safety of construction.
