2、倾覆稳 定计算,地基承载力计算,结构计算;并进一步根据地质条件和现场 要求进行优化设计。 以求达到安全适用的目的, 寻求最佳经济效益。 关键词:扶壁式挡土墙、土压力、荷载计算、结构、施工 II ABSTRACT Buttressed retaining wall is a kind of reinforced concrete thin wall type retaining wall, its main characteristic is simple structure, convenient construction, wall body section is small, its qu
3、ality is light, can better play to the strength of the material properties, and can adapt to the low bearing capacity of foundation. Relative cantilever retaining wall stress better, it is suitable for 6 12 m high embankment slope, can effectively prevent the fill slope sliding. The design analyzes
4、the principle of retaining wall; Analyzes the present situation of the application of retaining wall, research status and development trend; And complete the overall design of the buttressed retaining wall (proposed) main dimensions, load and the calculation of earth pressure, internal force calculation and sliding stability calculation, overturning stability calculation of foundation bearing capacity calculation, structural calculation. And to further optimize design according to the g
