摘　　要：基坑工程中选择合适的支护方案对保证施工过程的安全性有着重大意义。为提高深基坑工程支护方案选择方法的科学性与合理性,以武汉地铁12号线青菱站深基坑工程为依托,将TOPSIS(technique for order preference by similarity to an idea solution)法与AISM(adversarial interpretive structure modeling)法相结合建立了TOPSIS-AISM夹逼对抗解释结构模型,并将该模型运用于基坑支护方案优选中,通过对相关数据计算结果与评价指标体系进行分析,以验证该模型的合理性与科学性。结果表明:(1)该模型以哈斯图解的方式对各基坑支护待选方案进行分层优选,相较传统TOPSIS法其对各待选方案在具体工程项目中的优劣性表现更加全面;(2)该模型对指标赋权方法适应性强,依靠指标权重顺序信息即可得到科学合理的结果,相较传统TOPSIS法其更具排序稳定性;(3)该模型不依赖数据矩阵确定正、负理想点,相较传统TOPSIS法其评价标准更具有客观性与普遍性;(4)该模型可对具有活动因素特征的方案进行甄别,相较传统TOPSIS法其工程指导性更强.In the foundation pit project,the selection of the appropriate support scheme is of great signifi-cance to ensure the safety of the construction process.In order to improve the scientificity and rationality of the selection method of the support scheme for the deep foundation pit project,based on the deep founda-tion pit project of Qingling Station of Wuhan Metro Line 12,the TOPSIS(technique for order preference by similarity to an ideal solution)method is combined with the AISM(adversarial interpretive structure mod-eling)model to establish the TOPSIS-AISM clamping confrontation interpretation model,which is applied to the optimization of the foundation pit support scheme and the following conclusions are drawn by analy-zing the relevant data calculation results:①Themodel usestheHaasdiagramto select thefoundation pit support scheme to be selected in a hierarchical and optimal manner.Compared with the traditional TOPSIS method,this model has a more comprehensive performance of the advantages and disadvantages of each op tion to be selected;@The model is more adaptable to the empowerment method,and scientific results can be obtained by relying on weight order information,which is more stable than the traditional TOPSIS method;@The model does not rely on the data matrix to determine the positive and negative ideal points,which is more objective and universal than the evaluation criteria of the model in the traditional TOPSIS method;The model can identify schemes with activity factor characteristics,which is more instructive than the traditional TOPSIS method.
