龙厦铁路石桥头隧道地表建筑物变形监测方法及计算分析

石桥头隧道横跨龙岩市区，隧道长、埋深浅、岩质差、地表建筑物密集。在隧道开挖初期，建筑物出现较大沉降、倾斜、拉裂和错裂，严重影响建筑物正常使用，危及居民安全。为此对建筑物进行了沉降监测、水平变形监测和倾斜监测，并计算建筑物的曲率，取得很好的效果，且对隧道施工起到很好的指导作用，本文简要的研究了其监测方法及计算分析。

The Deformation Monitoring Method and the Computing Analysis of Building on ground surface at Long Xia Railway Shiqiao Tunnel

Shiqiao tunnel across Longyan,the tunnel long、buried deep、rock poor、the building on ground surface of the tunnel was dense.In the early stage of tunnel excavation,the buildings appeared large sedimentation、inclination、pull-and-error ,which had seriously affected the normal use of the buildings, endangered the safety of residents.therefor,we did settlement monitoring, level deformation monitoring and tilt monitoring for the buildings, and calculate the curvature of them,which obtained good results,and played a guide important for the tunnel excavation.this article compendiously researchs its monitoring methods and computational analysis.
