摘　　要：为探究整体现浇面板包裹式加筋土挡墙在交通荷载作用下的受力变形特性,以成昆铁路峨米段整体现浇面板包裹式加筋土挡墙为工程背景,利用现场监测数据并运用大型岩土有限元软件midas GTS对整体现浇面板包裹式加筋土挡墙进行了系统研究,实际工程中应适当增加挡墙中部筋带数量,减少加筋间距,增大加筋长度,采用短筋和长筋交替布置的方案,充分发挥筋材的加筋作用,加强挡墙整体稳定性。In order to study the mechanical deformation characteristics of rintegral cast-in-place panel wrapped reinforced soil retaining wall under traffic load,taking integral cast-in-place panel wrapped reinforced soil retaining wall of Emi Section of Chengdu Kunming Railway as the project background,a systematic study was carried out on integral cast-in-place panel wrapped reinforced soil retaining wall by using the on-site monitoring data and the midas GTS,the distribution law of parameters such as the deformation of integral cast-in-place panel wrapped reinforced soil retaining wall,the earth pressure of the retaining wall,the settlement of the base and the top of the wall was analyzed.In the actual project,the number of reinforcement strips in the middle of the retaining wall shall be appropriately increased,the reinforcement spacing shall be reduced,the reinforcement length shall be increased,and the alternative arrangement scheme of short reinforcement and long reinforcement shall be adopted to give full play to the reinforcement effect of reinforcement materials and enhance the overall stability of the retaining wall.
