| 摘 要： | 为探索大坝监控指标的研究方法,以飞来峡混凝土坝#18溢流段为例,利用强度储备法研究了坝段在初始屈服、临界失稳、失稳破坏三种特殊状态下监测点的水平位移分量值,并结合坝顶水平位移温度分量、时效分量的统计模型建立了该坝段水平位移的混合模型,拟定了#18溢流段的位移安全监控指标。

| Abstract: | In order to study the dam monitoring index,taking overflow section #18 of Feilaixia concrete dam for an example,the strength reserve method is applied to calculate the horizontal displacement component of monitoring points under the special conditions of initial yield,critical buckling and unstable failure.And then hybrid model of the dam horizontal displacement is established by combining the statistical model of temperature component and time-dependent component of the dam top horizontal displacement.Finally,the safety monitoring index of the displacement for overflow section #18 of Feilaixia project are obtained. |
