基于AHP的基坑支护方案的优选研究

Optimization of pile foundation program based on Analytic Hierarchy Process

基坑工程是一个复杂的系统工程,支护方案的优劣受很多因素影响,应用层次分析法原理,将复杂的深基坑支护方案决策问题层次化,并且,根据深基坑支护系统的特点建立层次结构模型,通过层次分析法比较,选出最优支护方案.实例研究表明,层次分析法简便、高效、科学合理,是一种处理复杂的多目标决策问题的实用方法.通过层次总排序得到各个备选方案的优劣排序,使选择过程更加全面、科学、公正、准确.

Deep foundation pit was a complex systematic project, supporting the merits of the program affected by many factors. This paper, through using analytic hierarchy principle, discusses the complex program of deep foundation pit hierarchical decision - making problems, and, under the Sbenzhen - based pit support system, it is characterized by the establishment of a hierarchical model and through the comparison of AHP to select the optimal supporting program. Case studies show： AHP is simple, efficient, scientific and rational, and it is a complex multi -objective decision - making problem in practical ways. Total sorting through the layers to be pros and cons of various options will make the selection process become more comprehensive, scientific, fair and accurate.
