“…Obviously, the instantaneous impact of flood has great influence on the bearing stability of engineering structures. However, the anchor structure of soil creep mechanics and anchoring force compensation research achievement are still rare, especially the flood load of soil slope failure mechanism, anchor aging stability evaluation of slope and anchorage parameters optimization design (Hobbs et al, 2011;Kurbanova et al, 2015). Many other problems have not yet completely solved.…”

In order to analyze the adverse effect of flood effect on slope stability, the analytical expressions of buoyancy force and capillary force, hydrodynamic pressure and impact force, and scour erosion were proposed based on the aging characteristics of soil shear strength and limit equilibrium theory. According to the load combination and flood action, shear failure occurs preferentially at the foot of slope. Then, the plastic zone continues to extend upward to produce traction landslide disaster mode. Furthermore, the power function relation between shear strength index and time was established. The nonlinear accelerated creep model was obtained. At the same time, the analytic formula of safety factor for flood loading effect slope aging stability, the time-varying characteristic value of anchor force and the compensation value of anchor force were also obtained. In addition, the numerical example shows that the slope safety factor decreases by more than 20% considering the effect of flood ascending scour and impact, and the compensation value of anchorage force increases obviously with time, and the change rate of compensation value of anchorage force increases nonlinearly with the increase of design safety factor.
