摘要:
西南山区某铁路双线特大桥开通运营以来，多个桥墩出现异常沉浮，对铁路运营产生了一定影响，铁路运输部门对通过此桥列车进行了限速。为查明桥墩异常升降的原因，文章以此桥为研究背景，结合地质补充勘察资料，分析了桥墩沉浮机理，提出了山区桥梁建设中需要重视的几个方面，对从事铁路勘察设计的工程技术人员具有很好的参考借鉴意义。
Abstract:
Since the operation, many piers of a double-track super-large railway bridge in southwest mountainous area sink and float abnormally, which has a certain impact on railway operation. Railway transportation departments have limited the speed of trains passing through the bridge. In order to find out the reasons for the abnormal sinking and floating of piers, this paper takes this bridge as the research background, combines with geological supplementary survey data, analyzes the sinking and floating mechanism of piers, and puts forward several aspects that need to be paid attention to in the construction of bridges in mountainous areas, which has a good reference significance for engineers and technicians engaged in railway survey and design.
