Study on Deformation and Stability of High Fills Soaked in Water under Earthquake
A two-dimensional dynamic numerical simulation model of high fills soaked in water is established with Geostudio software. Based on this, the deformation and stability laws of high fills soaked in water and the influence of water level of Three Gorges reservoir in response to earthquake are analyzed. The results show that the shear modulus of the soil layer decreases rapidly under the seismic inertia force, resulting in the larger shear deformation. The crack emerges because of connectivity of the shear deformation of the soft layer, the central interface and the top of slope, and the stability factor decreases sharply. Moreover, the minimum stability factor of high fill soaked in water under earthquake reduces with the raising of water level of the Three Gorges reservoir. Furthermore, the lateral and vertical displacement of the high fills soaked in water show obvious characteristic rules, and those displacements increase with the raising of reservoir water level.
