摘要: 目前,公路高切坡缺乏一个统一的分类,从而造成其破坏模式分析混乱,降低了公路高切坡治理的针对性和有 效性.因此,根据岩体结构面的控制性及现场易识性原则,将公路高切坡分成3大类9小类.依据岩性及其组合、岩体 结构、岩体强度、结构面间距、走向与边坡走向的关系、结构面倾角与坡角的关系等各种不同组合情况具体分析了公 路高切坡可能破坏的具体模式.在此基础上,提出了楔形体.平面滑动破坏模式、崩塌.滑动破坏模式、滑动-拉裂型破 坏模式及滑动.压裂型破坏模式等4种复合破坏模式,对高切坡的稳定性分析及潜在破坏面的识别具有指导意义.

关键词: 高切坡, 破坏模式, 分类, 稳定性分析

Abstract: At present,there isn't a uniform classification on the high-cutting slope along road.Therefore,this induces confu- sion in analyzing its failure models and reduces the pertinence and validity in governing the high-cutting slope along road.Ac- coming to control of rock fissure and easy identification in-situ,the authors classfied high-cutting slope along road 8.8 three big kinds and nine small kinds,and analysed the possible hflure models of every kind of high-cuting slope by lithology and its combination,rock fabric,rock intension,space between fissures,the relationship of fissures and slopes tend,the rela· tionship of fissures and slope's obliquity etc.Then four complex failure models of high-cutting slope are given:cuniform body-plane slide failure model,collapse-slide failure model,slide·tipping failure model,slide·crushing failure mod e1.These provide directions on stability analysis and recognizing of its failure fissures.

Key words: high-cutting slope along road, failure models, classification, stability analysis
