基于普通重力式泥石流拦挡坝，提出了一种新型泥石流拦挡坝。应用有限元分析软件LS-DYNA对新型坝和普通重力式拦挡坝进行了对比分析。结果表明：受到大块石冲击时新型坝后坝的应力分布更均匀，且应力明显小于普通坝，新型坝的冲击力、位移与普通坝相比明显降低。

Based on the ordinary gravity debris flow dam, this paper proposes a new type of debris flow dam. New de?bris flow dam and ordinary gravity dam are contrastively analyzed by finite element analysis software LS-DYNA. The results show that the stress distribution of new debris flow dam is more homogeneous than ordinary gravity dam when impacted by bulk stones, and has a smaller stress than the ordinary one. The impact force and displacement of the new dam are much smaller than the ordinary dam.
