Study On Stability Of Bank Slope With Flexible Structure Under Wave Action

In this paper,the flexible bank slope in the wave environment is taken as the object of study.The influence of the wave on the stability of the bank slope was simulated by numerical analysis method.The stress and seepage of the bank slope were analyzed with the dynamic change of the wave motion period.The schedule change rule of the bank slope safety factor was reached.The main research contents and results are as follows:(1)Explored the stability of slope under external loads.Considering the effect of external load on slope,the deformation and failure characteristics of slope are studied,and the influence of different external load,linear distribution and angle on slope stability is compared.The deformation and failure law of slope under vertical load is obtained.(2)A two-dimensional numerical model is established to simulate the hydrodynamic effects of wave propagation and breaking on the slope.According to the hydrological wave condition,the regular linear wave is used to simulate the wave motion,and the time fluctuation of the water level of the bank slope is analyzed.The variation of the size distribution of the wave dynamic load is obtained from the analysis of the water quality of the slope.(3)Calculated and analyzed the stability of bank slope under wave action.Because the wave load is the vector force with the intensity,direction and distribution changed with time,it has a high degree of time-varying,.In the analysis process,the wave load is equivalent to the static load,and the vertical bank slope effect hypothesis.Simultaneously,the effect of water level fluctuation on the slope is analyzed,and the stability of the slope is analyzed by the coupling of stress and seepage.The results show that the stability of bank slope is similar to that of wave motion...
