摘　　要：通过工程实例,分析了四川某大型全地下刚性填埋场结构设计的要点.结合工艺设计需要将扶壁式挡土墙和箱型截面悬臂式挡土墙运用于全地下刚性填埋场中,并分析了两种挡土墙结构在填埋场中的受力状态,为截面设计选型和配筋设计提供充分依据.根据场地条件,将填埋场底板依据受力情况的不同进行分区设计,兼顾经济性和工程可靠性.Through an engineering example,the key points of structural design of a large full underground rigid landfill in Sichuan are analyzed.Combined with the design process,the buttress retaining wall and box section cantilever retaining wall are applied to the full underground rigid landfill The stress states of the two retaining walls in the landfill are analyzed,which provides a sufficient basis for the design selection and reinforcement design of the cross section.Based on the site conditions,the bottom plate of landfill is designed by subzone according to the different stress conditions,and the economic efficiency and engineering reliability are also balanced.
