与普通路段的路面结构相比，交叉口路面结构暴露在更为复杂的交通特性下，可能会加剧路面疲劳开裂、推挤、剪切变形和车辙等病害。通过对上海十字路口交通特性的实地调查，建立了路面结构在匀速、加减速等不同交通特性下的力学响应的三维动态有限元模型。研究结果表明：(1)交通特征对路面最大主应变（MPS）和最大剪应力（MSS）的分布有显著影响；(2)车辆加速或减速对路面MPS和MSS的影响较大，可使路面MPS和MSS的幅度增加20% ~ 260%；(3)在垂直方向上，随着车辆减速度的增加，MPS峰值和MSS峰值的位置由次表层向路面变化。
Compared with pavement structures of ordinary road sections, pavement structures in the intersection are exposed to more complex traffic characteristics which may exacerbates pavement distresses such as fatigue-cracking, shoving, shear deformation and rutting. Based on a field survey about traffic characteristics in the intersection conducted in Shanghai China, a three dimensional dynamic finite-element model was developed for evaluating the mechanistic responses in the pavement structures under different traffic characteristics, namely uniform speed, acceleration and deceleration. The results from this study indicated that : (1) traffic characteristics have significant effects on the distributions of the maximum principal strain (MPS) and the maximum shear stress (MSS) at the pavement surface; (2) vehicle acceleration or deceleration substantially impact the MPS and MSS at pavement surface and could increase the magnitude of them by 20 percent to 260 percent; (3) in the vertical direction, with the increase of vehicle deceleration rate, the location of the MPS peak value and the MSS peak value changes from the sub-surface layer to the pavement surface.
