改进的可拓评价方法在坝体渗流评价中的应用

Application of Improved Matter Element Extension Evaluation Method to Dam Seepage Assessment

基于坝体渗流监测实测资料,构造了坝体渗流综合评价的物元可拓评价模型.针对传统评价方法在大坝渗流评价中的局限性,采用了更为简洁的权重选取方法,并将评价方法改进为更为简洁的基于最大贴近度、最大对比度的可拓评价方法.经工程实例验证,该模型合理有效,符合工程实际情况.

A matter element extension evaluation model for dam seepage evaluation is built based on the dam seepage monitoring data.Because of the limitations of traditional matter element extension evaluation method for dam seepage assessment,a new simpler choice of weight is built.And the traditional evaluation method is replaced by the maximal adjacency degree method and the maximal contrast method.A case study shows that the model is effective,rational and consistent with the engineering practice.
