| 摘 要： | 西南某高边坡位于317国道都（江堰）汶（川）路段,岷江右岸,距汶川县城约3 km.该边坡在汶川大地震中遭到局部破坏,影响到都汶公路的安全使用.通过物理模拟试验对该边坡在强震作用下的变形破坏进行研究和分析,最后得出该模型边坡表面对振动的反应比模型底部和内部有明显的放大现象,一般情况下反应的强度随边坡高度和坡度的增加而加剧.该边坡在强震作用下的破坏类型为滑塌式,表现为在滑动中滑体呈碎块状和碎屑状,边坡破坏的地质力学模式为滑移一拉裂型.

| Abstract: | A high slope belongs to the Dujiangyan to Wenchuan highway section of the national road 317,located at the right bank of Minjiang River,about 3km from Wenchuan County.The slope was local collapsed in the earthquake and threatened the road's security.The high slope deformation failure under earthquake is studied and analyzed by the physical simulation,the conclusion is that the response of slope surface is significantly larger than the ones on the bottom and internal in model,the reaction intensity is increa... |
