摘　　要：根据薄壳理论,应用ANSYS软件,采用参数化建模的方法对卵形消化池在静力荷载作用下的内力进行数值分析。通过对容积相同、池体尺寸按一定规律变化的卵形消化池的内力和表面积的比较,总结出在满足工艺要求下受力最为合理的结构形状,为初步设计阶段池型的选择以及主体尺寸的确定提供依据和建议。According to the theory of softhin shells, the egg-shaped digesters are modeled using ANSYS software and the internal forces under the static loads are analyzed. Through comparing the internal forces and the surface areas of the egg- shaped digesters which have the same cubage and regular change of dimension, the shape that satisfies the request of techniques and bears the force reasonably is obtained, and the advice of the option of the digester shape and the determination of the principal size in initial design phase is proposed.
