摘要
以穿越煤矿采空区某高铁线路为研究对象,经过对采空区场地现场勘查、物探测试、钻探验证,确定煤矿采空区的边界范围。基于采空区地表PS-InSAR沉降分析、采空区场地剩余变形预测分析以及技术经济比较,对拟选用的3个线路方案进行优化,确定出最终选线方案,并提出建议和措施,为类似工程实践提供借鉴和参考。
Taking a high speed railway line crossing the goaf of a coal mine as the research background, the boundary area of the goaf is determined through site investigation, geophysical exploration test and drilling verification. Based on PS-InSAR Subsidence Analysis of the goaf surface, prediction analysis of residual deformation of the goaf site and technical and economic comparison, the three schemes are optimized and the final route selection scheme is determined. Suggestions and measures are put forward to provide reference for similar engineering practice.
