摘　　要：近年来,一些大型热电厂、海运码头、大型煤矿企业,在其贮运环节中将贮煤的吨位容量提升到数万吨以至十多万吨,用钢筋混凝土圆筒仓来贮存,其高度又不能很高,一般在20m左右,因此,贮仓的直径就必须很大,达到120m或者更大。部分设计人将其仓壁设计成挡墙结构,另一部分仍设计成圆筒仓。在南方,夏季会很热,气温甚至可达38℃以上,仓壁外露其外侧温度必定很高,而仓内贮煤的温度一般在5～10℃左右。本文对考虑此仓壁内外侧温差时筒仓的温度应力计算进行探讨,供设计人员参考。In recent years,the storage capacity of the tonnage of coal was improved to several million tons in storage and transportation link in some large-scale thermal power plants,ocean ports and large coal enterprises.But with the reinforced concrete silos to store,which cannot be too high,generally about 20 meters,therefore,the diameter of silo must be large,may reach 120 meters or larger.Some of the wall of silos were designed as retaining wall structure, but some of them were still designed to round silo.In south,it＇s very hot in summer days,the temperature may reach 38 degree outside of silo,but it is low,about 5～10 degree inside of silo.The calculation of silo temperature stress were discussed considering the temperature difference between outside and inside of the wall,which could offer reference for designer.
