| 摘 要： | 由于影响土石坝安全的不确定因素较多,使其安全评价非常复杂.用集对分析方法构建样本与评价标准等级间的相对差异度函数,在此基础上,计算样本隶属于模糊集评价等级的相对隶属度,按求得的相对隶属度评定级别,并计算级别特征变量值,据此确定大坝综合安全等级.应用该评价模型对广东省白礤水库进行了安全评价,得到了该工程属于"二类坝"的结...

| Abstract: | The safety of earth rock dam has always been a focus issue in engineering field.In addition,due to various uncertainties,the safety evaluation of earth rock dam is complex.Functions of the relative deviation between the samples and the evaluation criteria are constructed by set-pair analysis.Then,we compute the relative membership degree of the fuzzy set evaluation grade of the sample;according to the relative membership degree,evaluation grade and characteristic variables are obtained.By applying this eval... |
