摘要
采用BISAR 3.0程序计算行车荷载在不同温度下两种柔性基层沥青路面结构的力学行为.荷载采用双圆均布垂直荷载,且为标准轴载BZZ-100,轮载P=25 k N,轮压p=0.7 MPa,半径d=0.106 5 m,层间接触状态为完全连续.通过计算结果分析比较路表弯沉、面层层底拉应力与剪应力以及基层层底拉应力与剪应力随温度变化规律情况,探索最优柔性路面结构形式.
BISAR 3. 0 was utilized to calculate two kinds of the mechanical behaviors of traffic load of flexible base asphalt pavement structure at different temperatures,the load was double circular uniform vertical load and the standard axle load BZZ-100,in which wheel load P = 25 kN,wheel pressure p = 0. 7 MPa,radius d = 0. 106 5 m and the contact state was completely continuous. Through the calculation,the change law with temperature of the road surface deflection,tensile stress and shear stress and the base bottom layer tensile stress and shear stress was studied and compared to explore the most flexible pavement structure.
