1、洛阳理工学院毕业设计（论文）洛阳某工程扶壁式挡土墙设计摘要扶壁式挡土墙是一种钢筋混凝土薄壁式挡土墙，其主要特点是构造简单、施工方便，墙身断面较小，自身质量轻，可以较好的发挥材料的强度性能，能适应承载力较低的地基。适用于缺乏石料及地震地区。一般在较高的填方路段采用来稳定路堤，以减少土石方工程量和占地面积。扶壁式挡土墙，断面尺寸较小，踵板上的土体重力可有效地抵抗倾覆和滑移，竖板和扶壁共同承受土压力产生的弯矩和剪力，相对悬臂式挡土墙受力更好，适用6～12m高的填方边坡，可有效地防止填方边坡的滑动。本设计剖析了挡土墙的作用原理；分析

2、了挡土墙的应用现状、研究现状及发展趋势；并完成了该扶壁式挡土墙的总体设计（主要尺寸的拟定）、荷载及土压力的计算，内力计算，滑移稳定计算，倾覆稳定计算，地基承载力计算，结构计算；完成了图纸绘制；设计了施工组织；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7洛阳理工学院毕业设计（论文）TheButtressRetainingWallDesignofaProjectofLuoyangABSTRACTHelpretainingwallisar
