摘　　要：文章以某市政道路边坡支挡结构物设计优化方案为研究背景,利用Midas/GTS岩土分析软件对原设计方案中桩体的几个关键指标进行分析,研究了原桩板墙设计方案中的边坡稳定性及桩体水平方向位移在不利工况条件下随着桩长、桩径两个关键指标的变化规律,最终根据分析结果确定了优化方案,节约了相关资源的投入。同时,也为类似工程设计和施工提供了建议和参考。With the design optimization scheme of slope retaining structure in a municipal road as the research background, this article analyzed the key indexes of the pile in the original design scheme by using the Midas/GTS geotechnical analysis software, studied the rules that the slope stability and the horizontal displacement of pile body in original pile-plate wall design scheme are changing with two key values of pile length and pile diameter under unfavorable working conditions, and finally deter- mined the optimization scheme according to analysis results, which saved the input of related re- sources.Meanwhile, it can also provide the recommendations and reference for similar engineering design and construction.
