摘要
结合变形实测资料,分别建立毛尖山大坝位移的统计模型和灰色模型,量化各影响因素对大 坝变形性态的影响程度,评价了大坝的变形性态。数值模型分析结果表明:大坝变形变化规律正 常,时效变化量趋于稳定。
The Maojianshan earth-rock dam, whose construction quality is not satisfactory, has been in operation for 40 years. According to the observational data of deformation, a statistical model and a gray model are established for the evaluation of the deformation behavior of the dam. The results from the numerical models show that the deformation of the Maojianshan earth-rock dam is normal and the time-effect variation tends towards stability.
