基坑支护方案模糊优选的改进层次分析法研究

Study on scheme's optimization of foundation pit support by improved Analytic Hierarchy Process

根据基坑工程特点和相关工程经验,建立相应的基坑支护结构评价指标体系,改进传统的层次分析法使其自然满足一致性检验,根据改进层次分析法计算所得的各备选基坑支护方案的重要性排序,可以对各个方案作出定量评价,并从中获得最优基坑支护方案。

Based on the characteristics and related experience of the foundation pit, an evaluation target system of related engineering was established, the synthesized weight of every shceme was calculated by improved Analytic Hierarchy Process, and this method could satisfied consistent verification naturaly. Based on the synthesized weight of every shceme, each scheme of foundation pit support could be evaluated quantitatively, and the optimum scheme among of them could be obtained.
