| 摘 要： | 利用界面单元模拟了不同交通等级条件下水泥混凝土路面板与二灰碎石层的接触状态,重点讨论了层间接触面粘聚力和摩擦角变化时,路面板的弯沉和层间剪应力的变化规律。研究表明:当接触面粘聚力一定时,轮隙处最大垂直位移(弯沉)随接触面摩擦角的增加呈现不规则变化;当接触面摩擦角一定时,最大弯沉和板中最大拉应力基本上随粘聚力的增加而增加,但当粘聚力大于10kPa,最大弯沉和板中最大应力均不再发生变化;在各级交通等级条件下,层间接触面的剪应力很小,不会发生层间的剪切破坏,因此,在施工过程中企图以增大层间粘聚力来提高施工质量的作法是不可取的。 |

| Abstract: | Interface element is used to simulate the contact condition of the cement concrete slab and the crushed stone base stabilized with lime and fly-ash under different traffic volume grades.The variation laws of slab's deflection and the shear stress between layers are emphatically discussed when the cohesion and friction angle of contact interface changes respectively.The results show that: when the cohesion of contact interface is constant,the maximum vertical displacement in the wheel gap(deflection) changes... |
