摘　　要：根据模糊积分的相关理论,对基于模糊测度的模糊积分加以改进,建立了有限集合上的模糊积分多元决策模型。在综合考虑影响深基坑支护结构选型各种指标因素的基础上,给出了基于改进的模糊积分深基坑支护方案优选模型,并归纳出应用该模型进行支护方案优选的一般步骤,编制了相应的计算程序。通过工程实例计算,验证了该方法的可行性与合理性。With the deep foundation pit project in the city gradually increased, the optimization of the deep foundation pit support scheme is particularly important. Based on the fuzzy integral theory, in this paper the fuzzy integral is improved based on fuzzy measure, and the fuzzy integral multiple decision model is estab-lished on the finite set. On the basis of comprehensive consideration of various index factors influencing the se-lection of retaining structure of deep foundation pit, the optimization model of deep excavation support scheme based on improved fuzzy integral is given. And the general steps of applying the model to optimize the support scheme is summarized. At the same time, the corresponding calculation program is developed. Finally, the fea-sibility and rationality of the method are verified by engineering examples.
