| 摘 要： | 对丹江口大坝３１号坝段具有代表性的测点的位移实测数据进行分析，并结合有限元计算，探讨了该坝段的变形监控指标。将大坝变形监控指标分为一般警戒值、特别警戒值和危险值三级，并分别用置信区间法、典型监测量的分量挑选法和平面弹塑性有限元计算为丹江口大坝３１号坝段拟定了它们的具体数值。这些变形监控指标可供该坝段实际运行观测时参考。

| Abstract: | Observed displacement data of the representative measuring points in the dam section 31 of Danjiangkou dam are analysed. In combination with computation using the finite element method, deformation monitoring indices for this dam section are dealt with. Values of dam deformation monitoring indices are divided into three categories: general alarming values, particular alarming values and danger values. Their numerical values for the dam section 31 of Danjiangkou dam are determined by using confidence interval method, Components of typical monitoring quantities choice method and planar elastoplastic deformation finite element method.These deformation monitoring indices can be used as references for observation of the dam deformation during practical operation of the dam. |
