煤矿采空区上桥梁变形监测

Transformation Monitoring on the Bridge over Coal Mine Goaf

近几年随着交通设施等基础建设项目的增加,经常会在一些容易引发不均匀沉降地质灾害的地段(矿山采空区、溶洞等上方)建设桥梁等重要建筑。如何有效地为基础建设提供保障,并为灾害治理提供合理建议成为测绘行业一个新的研究方向。通过分析在煤矿采空区上进行桥梁变形观测的实例,试图对变形观测的施工方案设计、数据分析的方法进行探讨。

With the development of transportation infrastructure in China in recent years, more and more bridges and other buildings are built on the areas where are under the unevenly subsidence geological hazard risk,such as coal mine goal and karst caves in mountain area. How to protect these infrastructures and prevent subsidence geological hazard is a key problem and a new research field in survey and mapping industry. Through the instance of transformation monitoring on the bridge over coal mine goaf, the paper researched and discussed the transformation monitoring implementation solution design and its monitoring data analysis methods.
