摘要
贵州省六盘水市风化玄武岩分布广泛,随着贵州西部高等级公路的快速发展,风化玄武岩类土质高边坡越来越多,部分边坡高度超100m。在详细现场调查、参考施工图详堪的基础之上,通过对正在施工建设的高速公路边坡工程实例进行分析计算,阐述了贵州六盘水境内风化类玄武岩的工程特性、边坡的设计原则及标准,讨论了类土质边坡的滑动力学模式、参数选择,通过迈达斯软件分析了边坡稳定性,为类似工程提供参考。
The air - slake whinstones in Liupanshui City of Guizhou Province are widely distributed. With the rapid development of high - grade highways in the west part of Guizhou Province, soil slopes of air - slake whinstones are more and more. The height of part of slopes has exceeded 100m. Basing on the detailed field investigation and detailed geological investigation of reference construction drawing, the analytical calculation is performed on the engineering project of slope of highway under construction, and the engineering characteristic of air- slake whinstones in Liupanshui City of Guizhou Province, design principle of slope and standard are elaborated. The sliding mechanical modes of soil slopes and parameter selection are discussed. The stabilities of slopes are analyzed through Midas software, providing reference for similar engineering.
