山区库岸路基防护结构物设置选型的模糊多属性决策方法

Fuzzy Multiattribute Decision Making Methods for Setup and Type Selection of Protective Structures of Roadbeds at Reservoir Bank in Mountainous Area

针对影响库岸公路路基防护与支挡结构稳定的各种因素具有随机性、不确定性等特征,运用非线性科学的模糊多属性决策方法进行山区库岸公路路基防护与支挡结构的优化选型,对防护与支挡结构的经济性、防护效果、使用寿命、施工可行性等进行模糊多属性决策,筛选出最优防护与支挡结构方案,使设计方案更加合理。

Aiming at features of randomness and uncertainty, etc. of various factors influencing stability of protective and retaining structures of roadbeds at reservoir bank, this paper utilizes non-linear scientific fuzzy multiattribute decision making methods to optimize selection of types of protective and retaining structures of highway roadbeds at reservoir bank in mountainous area, carries out fuzzy multiattribute decision making methods for economy, protective effect, service life and feasibility of construction, etc. of protective and retaining structures, and screens the optimal scheme of protective and retaining structures so as to enable more rationality of design schemes.
