改进层次分析法在深基坑方案优选中的应用

深基坑支护工程是一个复杂的系统工程,支护方案优选是深基坑工程设计系统中的关键环节。方案优选可视为一个多属性决策分析问题,层次分析法是一种适用于影响因素较多的复杂系统的决策分析方法,常被用于优选决策。采用带有自调节功能的改进层次分析法建立了深基坑方案优选模型,实例证明改进方法具有切合实际、易于接受与应用的特点。

Application of Improved Hierarchy Model on Optimum Decision- Making for Design of Deep Foundation Pits

The bracing engineering of deep foundation pit is a complicated system engineering,the optimum decision-making on bracing schemes is a key link in design system. Scheme optimization can be considered as a multiple attribute decision-making analysis problem,analytic hierarchy process is a method of analysis and strategic decision for the complicated system with more influential factors,it is often used for the optimal evaluation. Establishes an optimum model of bracing schemes for deep foundation pits through improved analytic hierarchy process with self-adjusting function,a case study shows the improved method is practical and easy to apply.
