摘　　要：高速铁路下伏采空区地基注浆治理的有效性是高速列车安全运行的关键。针对采空区的复杂性、注浆工程的隐蔽性及注浆效果难控制等问题,根据国家及地方规范文件、期刊文献和实证研究成果等3方面的基础资料,结合问卷调查和专家访谈方式构建了高速铁路采空区地基注浆治理影响因素体系。通过模糊DEMATEL方法研究影响因素之间的关联强度并识别关键因素,进一步基于ISM方法分析影响因素间的相互作用关系,建立层次结构模型。研究表明:注浆材料及性能是高铁采空区地基注浆治理的主要影响因素,对注浆效果作用程度最大;岩体基本质量和注浆材料及性能对注浆效果产生直接影响;开采方式、开采深度和煤层倾角等是注浆治理的深层因素;重复采动是影响注浆治理的最根本和最关键的因素。The effectiveness of foundation grouting treatment in goaf under high-speed railway is the key to the safe operation of high-speed trains. In view of the complexity of goaf,the concealment of grouting engineering and difficult control of grouting effect. Based on the basic data of national and local standard documents,journal literature and empirical study results,combined with questionnaire survey and expert interview,this paper constructs the influencing factors system of high-speed railway goaf foundation grouting treatment. The fuzzy Decision Making Trial and Evaluation Laboratory(DEMATEL) method is used to study the correlation strength between the influencing factors and identify the key factors. The interaction between the influencing factors is further analyzed based on Interpretative Structural Modeling(ISM) method,and the hierarchical structure model is established. The results show that grouting material and performance are the main influencing factors of foundation grouting treatment in high-speed railway goaf,which has the greatest impact on grouting effect. The basic quality of rock mass and grouting material and performance have a direct impact on the grouting effect. Mining method,mining depth and dip angle of coal seam are the deep factors of grouting treatment. Repeated mining is the most fundamental and key factor affecting grouting treatment.
