The paper presents a numerical analysis of soil-steel bridge with reinforced concrete (RC) relieving slab under static loads.Calculations were made based on the finite element method (FEM) using Abaqus software.Two computation models were used; in the first one,RC slab was used,and the other was without it.In all load schemes,the displacements are distributed relatively uniformly over the entire width of the steel shell.Maximal displacements are located at the shell crown and amountfm1 =2.33 x 10-3m and fro2 =0.78 x 10-3 m for the model without and with the RC slab,respectively.Maximal displacements were obtained from the load scheme No.Ⅲ.In addition,it was noted that vertical displacement distribution is a more uniform process in the model with RC slab than in the model without the slab.In the calculation model with RC slab,maximal stresses occur at quarter points (σn2 =10.2 MPa),and for the model without slab,the highest stresses (σml =56.2 MPa) are slightly shifted towards the shell crown.In both cases,maximal stress values were obtained from the load scheme No.Ⅱ.

粮食安全治理是国家治理的重要组成部分。本文主要对2004年新一轮粮改以来中国粮食安全治理的发展趋势、挑战及其成因进行了分析,并在此基础上提出改进中国粮食安全治理的相关建议。本研究认为,新一轮粮改以来,中国粮食安全治理的精准性、系统性和社会化水平不断提高,政府宏观调控作用、市场调节作用不断增强,财政投入力度和科技支撑作用不断加大,粮食安全保障水平稳步提升。同时,粮食安全治理面临资源和环境约束趋紧、生产成本高企、供求结构失衡、产业发展质量不高等挑战,而治理有效合力不足、中微观层次粮食安全观不明确、治理的法治化
