摘要
研究目的:为更好指导采空区铁路勘察选线工作,系统总结采空区铁路勘察选线设计的基本流程,提出采空区铁路选线安全距离计算方法、相关参数标准及选线途径。研究结论:研究表明,在不同等级铁路安全距离计算中,应采取相应的岩移角选取标准,高速铁路及无砟轨道客运专线应采用边界角,而普速铁路可采用移动角。结合工程实例,提出采空区铁路工程地质选线的方法和途径,包括线路方案比选——在矿区外围选线、局部方案优化——在矿区内选线,以及基于采空区变形计算和监测的铁路选线。
Research purposes: In order to guide the survey and railway alignment in the goal region, the basic procedures of the railway survey and alignment are summarized, and the computing method for the safety distance in the goal, the relative parameter and standard and the way for railway alignment are presented. Research conclusions:The study shows the boundary angle should be used for calculating the safety distance for high - speed railway and the passenger dedicated line of ballastless track, and the rock displacement angle should be used for calculating the safety distance for normal speed railway. Moreover, combined with engineering examples, the method and way for the railway alignment in goal are presented, including the comparison and selection of the railway alignments in the periphery of mining area, local optimization of alignment in the mining area and the railway alignment based on calculation and monitoring of the deformation of goal .
