边坡分级开挖过程的动态模拟

Achievement of Dynamic Simulation of Excavation of Slope in a Hydropower Station

利用有限元分析原理和ANSYS软件单元生死功能相结合的方法模拟某水电站后边坡的开挖过程,得到了开挖过程中边坡不同部位的变形、应变、应力分布及其变化情况。解决了边坡开挖动态模拟的难题,为以后的边坡开挖提供了很好的依据。

In this paper, slope excavating was simulated using the finite element method and the unit life and death of the AN- SYS function, and the distribution of the deformation, strain, stress in the different position in the process of excavation were recorded. The solution for dynamically simulating the slope excavation was presented and it provided a good basis for future similar projects.
