摘　　要：沪昆高铁丰城曲江段为采煤区。为了查明影响该段稳定性的主要因素,我们进行了地面调查、资料收集和钻探等工作,并利用钻孔点计算法进行了稳定性预测。结果表明,影响该区稳定性的主要因素是构造、岩性、煤层基本属性和开采现状等。以曲江矿井B4为例,对其稳定性进行了计算,在此基础上,通过地表变形计算及量化分析,对地面塌陷进行了易发性区划和风险评价,并提出了防治对策建议,为该地区城镇规划及重大工程建设提供了基础性地学依据。Qujiang segment of Shanghai-Kunming High-speed Railway in Fengcheng pass through coal miningarea. In order to find out the main influence factors of the stability, we conducted the ground survey, data collec-tion, drilling, etc, and predicted the stability by drilling calculation. The results showed that, the main influencefactors of the region stability are tectonic, lithology, basic attributes and exploitation status of coal, etc. Take themine B4 in Qujiang for example, the author calculated its stability. Based on this, we conducted stability zoningand risk assessment of ground collapse by surface deformation calculation and quantitative analysis, and put for-ward prevention countermeasure suggestion,which provided geological basis for town planning and major projectconstruction in the area.
