本文将非稳定渗流计算应用到河岸的稳定性计算中,构建模型推导计算水位变化与岸坡稳定性以及这一对变量的相对应调整过程。并运用以上原理通过某河流河段作为研究对象进行验证,计算某水位下代表安全性的稳定系数,且对涨水期、退水期、洪峰期的稳定性状态都进行了探讨,结果与实际测量资料一致。探讨了水位变化速率下稳定系数的变化特征,得出相应结论,即岸坡稳定性在退水和涨水两种不同速率下稳定性增长呈现减小和增大的两种不同走向。
In this paper, unsteady seepage calculation is applied to the stability calculation of riparian bank. The model is built to calculate the change of water level and the stability of bank slope and the corresponding adjustment process of this pair of variables. And the above principle is verified by a river section as a research object to calculate the stability coefficient of a certain water level which represents safety, and the stability status during the flood period, the return period and the peak period are discussed. The results are in good agreement with the actual The same measurement data. The variation characteristics of the stability coefficient at the water level change rate are discussed, and the corresponding conclusion is drawn that the stability of the bank slope decreases and increases in two different rates of return and flood.
