ANALYZING THE SEASONAL WATER LEVEL'S IMPACT ON DIKE EROSION USING GEOSLOPE SOFTWARE

Tóm tắt

Dike erosion during the rainy season is a common issue that significantly impacts the lives of people residing along the dike routes. One of the main factors contributing to the instability of dike structures is the formation of slip surfaces on the dike body as the water level fluctuates with the changing seasons. This study focuses on evaluating the stability of dike under seasonal variations in the river water level. The research employs two methods, namely the Finite Element Method (FEM) and the General Limit Equilibrium Method (GLEM), to assess the influence of geological parameters and soil drainage behavior on the dike's stability. The study aims to investigate potential instabilities in the dike's soil structure. The findings of the research indicate that using the SLOPE/W module of the GEOSTUDIO software with GLEM provides the recommended factor of safety (FOS). This factor is crucial in determining the stability of the dike under varying water levels, which can guide further actions to address potential erosion and ensure the safety of the dike and surrounding areas.
