| 摘 要： | 航道整治建筑物中的抛石丁坝水毁现象十分严重,其可靠性及使用寿命难以准确预测。针对这一问题,以非恒定流流量过程为控制条件,通过水槽物理模型试验,对"流量过程和最大冲深"这一组合进行了试验研究和计算方法研究,定义出抛石丁坝失效准则,采用基础统计理论,得出流量过程和最大冲深相结合的可靠度及使用寿命预测的概率模型计算方法。该方法对完善航道整治建筑物可靠度研究有一定的借鉴意义,还可为航道管理部门提供参考。

| Abstract: | The water damage of riprap spur dike in waterway regulation buildings is very serious and its reliability and service life are difficult to predict accurately.In order to solve this problem,the combination of flow process and maximum impact depth is studied experimentally and numerically through flume physical model test with unsteady flow process as control condition.The failure criterion of riprap groves is defined and the probabilistic model calculation method of the combination of flow process and maximum impact depth is obtained by using basic statistical theory.This method can be used for reference to improve the reliability of waterway regulation buildings,and can also be used as a reference for waterway management departments. |
