扶垛式挡土墙结构模型试验与优化设计研究
|
摘要
本文以大学生结构设计竞赛赛题中的挡土墙的设计与加载为例,为了研究模型的承载能力,以模型截面尺寸、结构尺寸为定量,通过加载试验,得到在竖向、对角、冲击三种情况下受力状态变化,再用Midas软件对模型的受力进行模拟,将实际数据与软件数据进行对比,并加以分析优化。进一步对模型优化设计后,制造出最适合三种情况下受力的扶垛式挡土墙结构模型,从而解决在受力易破坏的问题。
The paper takes design and loading of retaining wall in structure design competition for college students as an example, studies bearing capacity of research model, with model section and structure size as quantitative factors. Through loading test,stress state changes under vertical, diagonal and impact conditions can be obtained. After model stress simulation by Midas software,compare actual data with software data, analyze and optimize them. After further model optimization, structure model of buttress retaining wall suitable for three kinds of stress conditions is produced, to solve damage problem under stress.
