Stability Analysis of Excavated Bank Slopes for Silt Channel Remediation under Uneven Foundation Conditions
The current conventional methods of river bank stability analysis mainly extract the bank parameters by means of physical investigation and realize stability analysis by constructing a geometric model of the bank,which leads to poor analysis performance because the influence of geotechnical parameters on stability is not taken into account.In this regard,the stability analysis method of the bank slope of silt channel remediation excavation under the condition of inhomogeneous foundation is proposed.The influence of geotechnical parameters,hydrological conditions and slope geometry parameters on the stability of the bank is investigated by establishing a geometric model of the bank slope.The stability analysis is realized by analyzing the permeability mechanism of the soil inside the bank slope,selecting the stability calculation parameters,and finally calculating the bank stability structure coefficients and the displacement amount.In the experiment,the proposed method was tested for stability analysis performance.The experimental results show that the proposed method has a low error value in the displacement calculation when the geometric model of the river bank is analyzed,and has a more satisfactory analysis performance.
