摘    要:本文分析了混凝土面板堆石坝面板健康状态的影响因素,建立了面板性态初级评估层次结构图,并利用综合赋权法确定了各因素的权重。以模拟退火算法(SA)和改进的层次分析法(AHP)作为主观赋权法,将检验判断矩阵的一致性问题改进为求解非线性优化问题,得到了更加稳定准确的主观权重。同时结合BP神经网络的客观赋权法,通过基础样本对网络进行训练,利用BP神经网络的自动赋权特点客观地得出了各因素的客观权重。结合实际工程,采用Matlab编写程序,展示了主客观权重的算法耦合,客观间接地评估了面板的状态。

关 键 词:混凝土面板堆石坝  面板健康状态  层次结构模型  层次分析法(AHP)  模拟退火算法(SA)  BP神经网络

Abstract:The factors of the impacts on the health behavior of the face slab of concrete face rockfill dam are analyzed herein,and then the primary hierarchical structure for the evaluation on the behavior of the face slab is established and weights of all the factors are determined with the comprehensive weighting method. By taking the analytic hierarchy process(AHP)improved with the simulated annealing algorithm(SA)as the subjective weighting method,the verification of the consistency problem of the judging matrix is modified into the solution of the nonlinear optimization problem and more stable and accurate subjective weights are got. Meanwhile,combined with the objective weighting method of BP neural network,the objective weights of all the factors are obtained with the automatic weighting feature of BP neural network through the network training of the basic samples. In accordance with an actual project,the coupling of the algorithms for the subjective and objective weights is brought forth by the program compiled with Matlab,therefore,the behavior of the face slab is objectively and indirectly evaluated.
Keywords:concrete face rockfill dam   face slab behavior   hierarchical structure model   analytic hierarchy process(AHP)   simulated annealing algorithm(SA)   BP neural network
