开采沉陷区上覆浅埋管线灾害风险评价

Disaster Risk Assessment of Shallow Buried Pipelines over Mining Subsidence Area

对煤层开采引起的地表沉降进行计算,分析地表沉降对管道变形造成的影响,计算管道允许发生的最大沉降值。管线风险状况的评估需要对变形情况进行准确监测,并建立变形数据库系统,管线风险评价标准也需要进一步完善。

Calculate surface subsidence caused by coal mining,analyze the pipe deformation caused by impact of surface subsidence,and calculate the maximum subsidence value pipe allows. To assess the risk of the pipeline needs to accurately monitor deformation and establish a deformation database system,pipeline risk assessment standards also need further improvement.
