宝成线岳村大桥坐落于典型的覆盖型岩溶区 ,自 196 6年建成运营至 1999年未出现任何变形 ,1998某公司在大桥下游 140m处做深井抽水 ,于 1999年 6月桥基附近地面开裂 ,2 0 0 0年 6月大桥出现突然下沉变形。文章根据工程地质勘察及加固施工资料 ,论述了岳村大桥变形的根本原因和整治工程的设计思路 ,以期对遇到的同类问题有所借鉴
Baocheng Line Yuecun Bridge is located in a typical cover-type karst area, from 196 6 years of operation to 1999 did not appear any deformation, 1998, a company at 140m downstream of the bridge to do deep well pumping, in June 1999 near the bridge Ground cracking, bridge suddenly appeared in June 2000 deformation. According to the engineering geological prospecting and reinforcement construction materials, the paper discusses the root causes of the deformation of Yuecun Bridge and the design ideas of renovation project in order to learn from the similar problems encountered
