| 摘 要： | 土质为红层软岩破碎软弱夹层的临空边坡往往是不稳定的,其主要影响因素为边坡的坡度、降水及上覆荷载等.本文对此进行了室内模型试验,给出了降水量与坡角的关系曲线、渗透深度与坡角的关系曲线,以及定性描述上覆一定厚度黄土层时的破坏特征,分析了破坏产生的原因,同时给出了坡率及降水引起边坡滑塌的最大坡角的定量界限.

| Abstract: | The exposed slope with the soil of soft sandwich in red-layered soft rock is often instable,and its main influencing factors are the slope,precipitation,and overburden on the slope.An indoor experiment on the slope model was conducted.The dependence of slope angle on precipitation and that of slope angle on seepage depth were given.The destruction feature of the slope with a definite thickness of loess layer was qualitatively described and its origin was analyzed,also.Meantime,a quantitative limit of maximum slope angle for the slope collapse due to the slope and precipitation was also given. |
