| 中文摘要: |
| 利用ABAQUS对某改建公路的路面结构方案A和方案B进行研究，建立具有完整路面宽度的三维有限元模型，水泥路面接缝采用弹簧单元进行模拟，以便划分出不同大小尺寸的水泥混凝土板.然后载入标准轴载、超载20%、超载40%、超载60%时荷载，计算在均质稳定路基情况下水泥混凝土板的拉应力以及弯沉变化，分析A、B两个方案路面结构的优劣. |
| 英文摘要: |
| We study A and B pavement structure programs of some road reconstruction by ABAQUS software,and establish three-dimensional finite element model of the full width of the road.Joints of cement concrete pavement is simulated by spring element,in order to be carved out of the different sizes of cement concrete slab.And we load the standard axle load,with an overload of 20%, 40% and 60% ,to calculate the tensile stress and deflection changes of the cement concrete slab in the case of homogeneous and stable roadbed,and analyze the pros and cons of pavement structure of A,B two programs. |
