摘要
巴鹤公路是恩施州东北部地区一条重要的二级公路,通过分析公路沿线的区域地质环境背景,结合公路线形特点、结构形式,指出了研究区常见的病害和诱因。遵循"地质过程机制分析"的方法,将岩质边坡病害分为"松动卸荷带"、"滑移—拉裂"、"滑移—弯曲"、"弯曲—拉裂"和"坠腔"型5种类型,分析了各类型病害的发育特征和变形破坏机制,提出了有针对性的防治措施,以期达到有效治理病害的目的。
The Badong-Hefeng highway in northeast Enshi is an important provincial road.On the basis of the alignment characteristics of geological environment,expressways and structural styles in an alpine area,the common slope diseases and the induced-reasons are revealed.According to the geological process mechanism analysis,rock slope diseases are divided into the following five categories： ＂unloading zones＂,＂sliding and fracturing＂,＂sliding and bending＂,＂bending and fracturing＂and＂falling cavity＂.The paper analyzes the various types of characteristics and deformation failure mechanism,the prevention methods are put forward,which could achieve the purpose for effectively preventing diseases.
