摘要
为了更好地比选滑坡综合治理方案,针对影响治理方案因素的复杂性和不确定性,以安全可靠性、环境协调性、经济合理性、技术可行性、施工难易、施工工期等做为评价因子,建立了基于熵权决策法的滑坡综合治理方案比选评价模型。根据专家意见建立判断矩阵,利用熵权决策法的原理确定"理想点";通过计算4个设计方案与"理想点"的贴近度与距离来确定方案的排序。结果表明,方案二(锚索抗滑桩与截排水相结合)为最优方案。熵权决策法克服了传统评估方法中主观确定权数的缺陷,保证计算过程和结果的客观性,是一种可行的、定量的滑坡治理方案比选方法。
In order to compare various landslide control schemes and find an integrated control scheme,an optimization approach is established based on entropy weight.Such factors as geological information,practical condition,engineering economy and environmental influence are incorporated.According to the opinion of experts,a comparison matrix is set up.Entropy of decision-making is used to determine the "ideal point".The order of schemes is determined by calculating the close-degree and the distance between the four...
