摘要
针对东坡煤矿至刘家口选煤厂带式输送机输煤系统在平朔露天煤矿专用铁路K12+965处下方穿过的问题,采用数值模拟的方法,对皮带走廊初期支护条件下变形情况进行了数值模拟。计算结果显示,地下走廊暗挖施工穿越铁路专用线对铁路运营及地表变形影响甚微,完全在规范允许范围之内,分析结果对工程设计与施工有重要的指导意义。
For the problem of Dongpo Mine to Liujiakou Coal Preparation Plant conveyor coal transportation system crossing the below of Pingshuo Mine opencast special railway in K12 ＋ 965, the method of numerical simulation was adopted, the deformation conditions of the belt corridor under the initial support were simulated. Calculation results showed that the underground corridor construction through railway sidings had little impact on railway and the surfaee deformation, completely in the range of specification, the analysis results had important guiding significance on engineering design and construction.
