镇胜高速公路沿线丘陵山地广布,地形地貌复杂多变,地层岩性软硬分布不均,地质构造发育,岩体破碎,边坡工程问题非常突出。该文对镇胜高速公路高边坡变形类型、坡体结构类型及变形破坏模式进行详细分类并对每种类型的特征进行了归纳总结。在此基础上,针对高边坡的复杂性及治理难度大等特点,建立与之对应的高边坡优化设计模式,确定了“全面普查,重点研究”的思路,同时筛选了其中10处高边坡为重点研究对象。对重点高边坡采用“变破坏机理研究—稳定性评价—边坡安全监测—边坡支护”的思路进行优化设计。
The highway along the town wins a wide range of hills and mountains, the topography is complex and changeable, stratigraphic lithology is not uniform distribution of hard and soft, geological structure, rock crushing, slope engineering problems are very prominent. This paper classifies the deformation type, slope structure type and deformation failure mode of high slope of Zhensheng Expressway in detail and summarizes the characteristics of each type. On the basis of this, aiming at the complexity of high slope and the difficulty of treatment, the corresponding high slope optimization design mode was established and the idea of “comprehensive survey and key research” was established. Meanwhile, 10 High slope as the focus of research. Optimize the design of key high slopes using the idea of “research on variable failure mechanism - stability evaluation - slope safety monitoring - slope support”.
