| 摘 要： | 对龙井滑坡的形成原因进行了探讨。滑坡对应路基为深挖路堑段,呈顺倾产状,坡脚临空;坡体内白云岩部分泥化,且受到基岩裂隙水浸泡和风化作用,致使其抗剪强度降低,坡体稳定性下降;人类活动和大气降水则促使滑坡变形进一步发展。利用软件计算了三个断面的剩余下滑力,并提出了治理方案。

| Abstract: | The slippage of Longjing slope has occurred in course of the construction of highway roadbed.Based on the analysis of the geological condition and character of Longjing slope,the causes of landslide are discussed.The roadbed of landslide is constructed by large-scale slope excavating and along with the lean direction of terrene,which causes the slope to slide along this direction.At the same time,dolomite is mudded partially,dipped in the cranny-water and airslaked, which weakens the strength of the rock and soil and makes the slope instability.The residual drive-down forces of 3 cross-sections are calculated,then the treatments are presented. |
