飞来峡水利枢纽船闸闸墙顶水平位移安全监控指标拟定及应用

根据飞来峡水利枢纽船闸的原型监测资料，选取每年运行过程中最不利工况时闸墙顶水平位移监测效应量作为计算序列，应用典型小概率法，对船闸闸墙顶的水平位移安全监控指标值进行了研究拟定，并结合2012年的实测值，分析了船闸闸墙的运行状况，结果：在环境量变化与往年基本一致的工况下，2012年典型闸段闸墙顶的水平位移值均小于安全监控指标。

Determination and application of ship lock wall top horizontal displacement safety index for Feilaixia Hydraulic Complex

From the prototype ship lock monitoring data of Feilaixia Hydraulic Complex, the lock wall top horizontal displacement monitoring effect quantities under the most unfavorable operating conditions of each year were selected as calculating sequence, based on which the lock wall top horizontal displacement monitoring safety index were studied and determined by small probability method. Combine with the observation records of 2012, the author ana- lyzed the operation status of ship lock wall. The results of analysis demonstrate that the environmental amount variation was generally identicul with that of former years, and the lock wall top horizontal displacement of typical lock wall sections were less than the monitoring safety index in 2012.
