Research on Concrete Road Structure Design for Grain Depots of Different Capacities
In this paper,the structural layer design of concrete pavement in grain depot is studied.First of all,based on the road traffic volume,considering the particularity of the grain depot,and considering the grain rotation cycle and traffic growth rate,the annual traffic volume of the road in the reservoir area is determined.Then,the grain truck structure model is simplified to determine its axle load under full load condition,and the standard axle load conversion is carried out to determine its traffic load grade.Finally,based on the elastic foundation slab theory,the grain depot with different tonnage is calculated,and the design number that should be considered in the design of pavement structure layer under different working conditions is defined,in order to provide a certain reference for the subsequent design.
