摘　　要：进行了波形钢腹板PC组合箱梁约束扭转试验,并利用ABAQUS软件进行有限元模拟,对影响抗扭刚度的相关参数进行了分析。结果表明:高跨比较大时,横隔板对抗扭刚度的影响较大;波形钢腹板的倾斜角较小时,波形钢腹板的倾斜设置对抗扭刚度的影响较小;当波形钢腹板倾斜角的正切值大于1/5时,抗扭刚度的提高幅度大于10%。The constrained torsional experiment of a PC composite box girder with corrugated steel webs was carried out and some related parameters of influencing torsional rigidity were analyzed by using finite element method with software ABAQUS. Results show that when the depth-span ratio is large, the cross wall has more influence to the torsional rigidity; when the inclination angle of corrugated steel webs is small, inclined set of corrugated steel webs has a little influence to the torsional rigidity, but when the tangent value of inclination angle of corrugated steel webs is more than 1/5, the torsional rigidity can improve more than 10%.
