| 摘 要： | 对飞来峡主土坝1 025剖面采用强度储备法进行二维有限元计算,得出在不同上、下游水位组合下大坝分别出现初始屈服、临界失稳、失稳破坏三种状态时特征点的水平位移,并用二元二次回归方法建立特征点的水平位移与上、下游水位的关系模型,进一步拟定了飞来峡主土坝1 025剖面水平位移的监控指标。

| Abstract: | It is applying strength reserve method to carry out the calculation of two-dimensional finite element for section 1 025 of main earth dam of Feilaixia in this paper,work out the horizontal displacement of characteristic point under combination about different water level upstream and downstream when the dam is at the three states of initial yielding,critical instability and unstable failure,and establish the model of the relation between horizontal displacement and upstream and downstream water level with dualistic and quadric regression method,then gain the safety monitoring index of horizontal displacement of section 1 025 in main earth dam of Feilaixia further. |
