摘　　要：结合地铁施工的特点,分析地层位移对邻近建筑物的损害形式,明确地铁施工引起地层位移对邻近建筑物安全影响的主要风险源,从而建立相应的评价指标体系;采用熵权法和模糊综合评判相结合的综合评价方法,建立风险评价模型;最后进行实证研究,结果表明具有较强的可靠性。The thesis combined the characteristics of subway construction, analyzed the damage form of strata displacement to the neighbouring building, defined the main risk source of the strata displacement caused by subway construction to the neighbouring building about its safety, and then, established the corresponding system of evaluation; The thesis used comprehensive evaluation method which combined with entropy and fuzzy, built the risk evaluation made. Finally, the thesis made an empirical comparison, the results showed that the method bad strong reliability.

关 键 词：地层位移 熵权 模糊综合评价 风险指标体系
