Wall Structure Analysis And Comparison For Large-Diameter Reinforced Concrete Underground Silo

Green grain storage is a contemporary development trend of grain storage,and it also isan important direction of implementing strategy of sustainable development. Due to manyproblems not conducive to green grain storage about the ground granary exploiting andutilizing the underground space to store grain becomes very meaningful.In such long-term low-temperature safe storage, saving cost and reducing chemicalpollution, resisting natural damage and so on, the existing underground granary hasdemonstrated unparalleled advantages and can achieve the target of green grain storage.Large-diameter reinforced concrete underground silo is one form of underground granary.Large-diameter reinforced concrete underground silo not only inherites the advantages ofground silo, but also overcomes many defects of the existing underground granary, such aslow level of mechanization, small storage capacity, limit in terrain, difficulty in constructionand so on.Based on the study of theoretical calculation method about cylindrical structure,drawingsupport from the model of cylindrical structure under considering shear deformation effects,this paper derives additional items under arbitrary load and initial parameter solutions underdifferent boundary conditions, verifies the applicable scope of initial parameter method byANSYS, and applies initial parameter method to calculate the changes of internal force anddisplacement for large-diameter reinforced concrete underground silo wall in the differentstages of filling the earth and grain. By ANSYS,this paper analyses material nonlinearanalysis for large-diameter reinforced concrete underground silo wall, makes clear thecharacteristics of the silo wall, points out the weak parts of the silo wall under loads, digs upthe potential performance of reinforced concrete, and discusses the influencing factors of silothickness. Combined with initial parameter method and silo thickness determined by ANSYS,this paper discusses the influencing factors of internal force and displacement oflarge-diameter reinforced concrete underground silo wall, and compares the wall mechanicalperformance and economic performance of different schemes.The study purpose of this paper is to provide evidence and reference for future structuraldesign and experimental study of the subject.
