通过对汶川桃关沟泥石流下游浆砌块石坝损毁特征调查，发现该类坝体受块石冲击后坝体结构表面拉裂或碎裂，产生大变形，形成凹坑等，受后期泥石流体的冲击损坏。按1∶1建立数值仿真模型，数值仿真结果显示，坝体损毁特征与调查的结果基本一致，坝体受到的大块石冲击力与理论计算的值相差约14.04％，数值仿真的结果在一定程度上可以指导该类坝体的设计及后期修复治理工作。

By investigation of the damage features to the dow nstream mudslides slurry dam blocks in Taoguan Ditch in Wenchuan ,we found the dam surface has some of shock rock cracks or shatters ,larger deformation and pits in varying degrees by the impact of debris flow solid matters .We establish numerical simulation model in proportion of 1∶1 .The numerical simulation results show that the dam damaged val-ues of simulation are consistent with the results of the field investigation ;the disparity between theoretical algorithms and measured value by the impact of a large stone is 14 .04% .T he results of numerical simula-tion can be used for guiding this kind of dam designs ,prevention and control after disaster .
