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。
Combined with the characteristics of subway construction, this paper analyzes the damage forms of adjacent buildings caused by formation displacements, clarifies the main risk sources of the influence of formation displacements on the safety of adjacent buildings, and establishes the corresponding evaluation index system. By using entropy method and fuzzy comprehensive evaluation A combination of comprehensive evaluation methods, the establishment of risk assessment model; the last empirical study, the results show that with strong reliability.
