铁路桥沉降观测及桥下采煤安全措施的探讨

摘  要：随着我国煤炭资源开采力度的逐渐增大，铁路下压煤问题越来越严重。如果不对铁路及其周围建筑物进行有效的保护，而直接开采煤炭资源，将会因为地表变形而引起铁路桥梁沉降变形等情况。基于此，文章重点结合实际案例，针对铁路桥沉降观测进行了分析，并提出了相应的桥下采煤安全措施，以供参考。

Abstract： With the gradual increase of coal resources mining in China， the problem of pressing coal under the railway is becoming more and more serious. If the railway and its surrounding buildings are not effectively protected， but coal resources are exploited directly; therefore， the settlement and deformation of railway bridges will be caused by surface deformation. Based on this， the article focuses on the actual case， analyzes the settlement observation of the railway bridge， and puts forward the corresponding safety measures of coal mining under the bridge for reference.

Keywords： railway bridge; settlement observation; coal mining under bridge; safety measures
