| 摘 要： | 危岩失稳是三峡库区频发的地质灾害之一。文章在研究凤城危岩所处区域的地质背景条件及危岩失稳的诱发因素基础上,分析了凤城镇危岩体的分布规律及形态特征,根据破坏模式的不同对该区危岩进行了类型划分,采用赤平投影法与极限平衡法对该区6个代表性危岩单体的稳定状况进行定性与定量分析评价,经分析判断其均处于欠稳定或不稳定状态,需进行工程治理。针对每个危岩单体的具体特征,提出了小规模清方+岩体支撑+锚固,配合地表排水及裂隙封闭的联合治理方案。

| Abstract: | The failure of dangerous rock is one of the geological disasters that occurs frequently in the Three Gorges Reservoir area.Based on the study of geological background conditions and the factors inducing the failure of dangerous rocks,this paper explains the distribution and morphological characteristics of dangerous rocks in Fengcheng town,provides the classification of the failure modes of the dangerous rocks in this area,and analyses the stabilities of six representative monomers of dangerous rocks qualit... |
