摘　　要：以某新型钢波纹板-混凝土组合式拱涵为研究背景,基于经典力学理论,将钢混组合式拱涵简化为平面应变问题,推导了其内力、强度及稳定性计算公式,同时建立ANSYS有限元模型,得到了强度及稳定性近似解。计算结果表明:钢波纹管-混凝土组合拱涵施工过程中最大Von mises应力为46.1 MPa,混凝土最大拉应力0.59 MPa,最小一阶稳定系数126.51,强度及稳定性均满足规范要求。A new type of steel corrugated plate-concrete composite arch culvert is taken as the research background.Based on the classical mechanics theory,the steel-mixed composite arch culvert is simplified to the plane strain problem,and the internal force,strength and stability calculation formula are derived,By using ANSYS to establish the finite element model,getting an approximate solution of strength and stability.The calculation results show that the maximum Von mises stress of steel bellows-concrete composite arch culvert is 46.1 MPa,the maximum tensile stress of concrete is 0.59 MPa,and the minimum first-order stability coefficient is 126.51.The strength and stability meet the requirements of the specification.
