摘要:
为了解决泥石流拦挡坝在泥石流发生时容易被大块石损毁的问题，提出了一种具有自复位功能的泥石流拦挡坝，并采用钢球代替泥石流中的大块石，运用有限元软件ABAQUS对其进行冲击模拟，从坝体的变形、支反力、位移、加速度等方面与普通重力式泥石流拦挡坝进行了对比分析。结果表明：自复位拦挡坝较普通重力式泥石流拦挡坝有良好的抗冲击性能，其应力小且分布比普通重力式泥石流拦挡坝更均匀，支反力和加速度较普通重力式泥石流拦挡坝有显著降低，位移略大于普通重力式泥石流拦挡坝。
Abstract:
In order to solve the problem that ordinary dam was easily damaged by boulders in debris flow, a selfcentering dam was proposed, and steel ball was used instead of large debris flow stone. The new type debris flow dam was simulated under the impact of large debris flow stones by using finite element software ABAQUS. The analysis of comparison between the self-centering dam and ordinary gravity dam was made on deformation, reaction force, displacement and acceleration. The results show that compared with the ordinary gravity dam, the selfcentering dam has superior impact resistance and its stress distribution is more homogeneous and smaller than ordinary gravity dam. The reaction force and acceleration are much smaller than the ordinary gravity dam, but the displacement is slightly larger than the ordinary one.
