大面积深埋采空区对铁路工程建设影响研究

Research on the Influence of Large-area Deep-buried Goaf on Railway Engineering Construction

以通过鲁西南黄淮海冲洪积平原区深埋大面积煤矿采空区的铁路工程为例,论证研究建设方案的可行性,经理论计算分析和数值模拟,并将计算结果同第三方变形监测结果进行对比,表明特定条件下采空区地表变形轻微,达到沉降稳定历时时间短,对铁路安全运营无影响,适宜铁路工程建设。

Taking the railway project passing through the deep-buried large-area coal mine goaf in the Huanghuaihai alluvial-proluvial plain area in the southwest of Shandong Province as an example,in order to demonstrate the feasibility of the research construction plan,theoretical calculation analysis and numerical simulation are carried out,and the calculation results are compared with the third-party deformation.The comparison of the monitoring results shows that under certain conditions,the surface deformation of the goaf is slight,and the time to achieve stable settlement is short,which has no impact on the safe operation of the railway,and is suitable for railway engineering construction.
