摘　　要：提出一种超大直径低壁浅仓圆环壳体结构无矩理论模型,该壳体底部径向可滑动,壳体内力基本呈无矩内力状态,其温度应力、边缘效应和地震作用可降为最低。计算与分析表明,提出的圆环壳体结构无矩理论模型相对于挡土墙模型可极大幅度地节省材料、缩短施工工期及降低工程造价,是超大直径低壁浅仓结构形式研究的优化方案和最新进展。In this paper,an annular shell structure membrane model for shallow silos with large diameter is presented.The bottom of the shell is slidable in the radial direction,and the shell is basically in the state of no internal moment.Its temperature stress,edge effect and earthquake action could be reduced to a minimum.Calculation and analysis show that the proposed model of the annular shell structure can greatly save structural materials,shorten construction time and reduce cost of the projects.It is an optimal scheme and the latest development of the study of the structure of large diameter shallow silo.
