摘要
深基坑支护方案的选择主要可以从安全可行、经济合理、环境影响以及施工技术这四个大的影响因素考虑。为了更加严谨的选出深基坑支护方案,需对这四个因素进行分层考虑,由此引入层次分析法,建立层次结构模型图,计算出各指标因素权重,再通过模糊综合评价法,计算各支护方案总综合评价值,从而确定最优支护方案,结合工程实例验证了该方法的可行性。
The choice of deep foundation pit support scheme can be mainly considered from four major influencing factors,such as safety and feasibility,economy and rationality,environmental impact and construction technology.In order to select the deep foundation pit support scheme more rigorously,it is necessary to consider these four factors in layers.Therefore,the analytic hierarchy process(AHP)was introduced to determine the optimal support scheme.The hierarchical structure model diagram was established,the weight of each index factor was calculated,and then the total comprehensive evaluation value of each support scheme was calculated by fuzzy comprehensive evaluation method.Combined with an engineering example,the feasibility of this method was verified.
