2、程性质，初步确定边坡大多需要支护。支护类型大致 确定为重力式挡土墙支护和单点排桩支护。而分析用和支护大致取决于边坡的坡高 和深度，因为本道路主要用于铁路所以对于坡体具有深度的一般采用重力式挡土墙 来支护， 支护后对于后面边坡可直接采用刷坡进行处理。 而对于坡体不高于 10 米都 可采用重力式挡土墙来支护，支护后对于后面边坡采用刷坡进行处理。对于高度大 于 10 米的边坡，一般考虑使用适合本路段的单点排桩支护。为了节约施工材料，要 对桩长进行适当的处理，节约成本。本边坡支护工程要考虑边坡支护的合理性，施 工的可能性，还有经济的节约性。所以本边坡支护设计方案在满足边坡稳定性的情 况下兼顾降低工程造

The design for the total lengt

4、h of 180 meters, the slope height of 1.84-27.39 meters, depth of 9.69 meters -15.72 meters of slope. This section of the road complex terrain, geological mostly sand, supporting more difficult, analyze its engineering properties, preliminary determine the slope most in need of support. Supporting ty

5、pes generally identified as gravity retaining wall supporting and single row pile retaining. The analysis and support generally depends on the slope of the slope height and depth, because the road is mainly used for railway with depth for the slope by gravity type retaining wall to support, support

6、for the back slope can be directly used for treatment of slope. As for the slope is not higher than 10 meters can be used to support the gravity retaining wall, support for behind of slope by slope treatment. For more than 10 meters height of slope, generally considered suitable for the section of the single row pile retaining. The saving construction materials, the pile length for proper treatment, cost savings. The slope to slope support account of rationality, the possibility
