摘　　要：软土地基中的蛋形消化池基础设计,通常采用大直径的钻孔灌注桩。本文所述大直径预应力混凝土管桩首次在蛋形消化池中成功应用的工程实例,表明该类桩型能减少工程造价、缩短施工周期、控制构筑物的沉降变形。本文主要论述了软土地基中蛋形消化池采用大直径预应力混凝土管桩设计时应注意的要点,为类似设计提供参考。The bored piles of large diameter are usually designed as the foundation of the egg-shaped digester in soft soil.The first application that the prestressed concrete pipe piles of large diameter are successfully used in the egg-shaped digester showed this kind of piles can reduce the construction cost,shorten the construction period and control the structure settlement.This paper discussed some key points which should be noted in the application of large-diameter prestressed concrete pipe piles in the egg-shaped digester in soft soil foundation.
