摘要
针对混凝土坝实际监测项目和测点布置情况,在现有综合评价模型的基础上,提出综合考虑客观实际与系统专家意见大坝安全综合评价PP-AHP模型。在计算得到加权权重后,进一步考虑指标间的相关性,根据Gram-Schmidt的思想,对指标作正交化处理消除了指标信息重叠对评价结果的干扰。工程实例验证了PP-AHP模型对混凝土坝进行安全综合评价的优越性。
According to the actual monitoring project and the measuring points arrangement of concrete dam, the PPAHP model which take into account objective reality and expert advice is proposed based on the existing comprehensive evaluation model. After calculating the weighted weights, the correlation between the indicators is further considered. According to the idea of Gram-Schmidt, the orthogonal processing of indicators eliminate the interference of overlapping information on the evaluation results. The engineering example verifies the PP-AHP model is superior for the safety comprehensive evaluation of concrete dam.
