摘　　要：深基坑工程变形往往有多个评价指标,但在工程实践中,各个评价指标往往不在同一范围内,这给深基坑工程的整体安全性评价带来了困难。文章利用可拓学理论建立了深基坑工程安全评估模型,通过计算深基坑安全的关联函数,对各评定等级的符合程度而做出综合评定,把深基坑安全评估由定性评估转化为定量评估,并以某深基坑工程为示例,利用建立的数学模型对该深基坑工程进行了评估,评估结果表明了该方法的可应用性。For the deformation of deep excavation there are several evaluation factors and the safety degree of the factors is generally not in the same range. It brings about a lot of difficulties for evaluating deep excavation safety during its construction. Based on the extension theory, a comprehensive evaluation model of deep excavation safety was proposed by calculating the dependent degree of deep excavation safety. It transformed the qualitative evaluation method into quantitative evaluation. As an example, a deep excavation safety was evaluated, the results show that the new method is applicable to evaluate the deep excavation safety.
