摘　　要：运用ABAQUS软件来控制混凝土等级、剪跨比以及配箍率的不同来模拟铁尾矿砂浮石混凝土梁的抗剪性能.模拟结果分析表明:剪跨比的减小、混凝土强度的提高、配箍率的增大可以使得混凝土梁的抗剪承载力得到提高.Abaqus software is used to control the concrete grade,shear-span ratio and stirrup ratio to simulate the Shear behavior of iron tailings pumice concrete beams.The results show that the shear bearing capacity of concrete beams can be improved by decreasing shear-span ratio,increasing concrete strength and increasing stirrup ratio.
