大型全地下刚性填埋场结构设计

本文通过工程实例,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。

Structural Design of Large-scale Full Underground Rigid Landfill

SThrough the engineering example, this paper analyzes the key points of structural design of a large underground rigid landfill in Sichuan. Combined with the process design, the buttress retaining wall and box section cantilever retaining wall are applied to the underground rigid landfill. The stress state of the two retaining walls in the landfill is analyzed, which provides a sufficient basis for the design and reinforcement design of the cross section. According to the site conditions, the bottom plate of landfill is designed in different zones according to the stress conditions, taking into account the economic and engineering reliability.
