| 摘 要： | 通过对不同表面处理方式的传力杆和对摆放位置存在偏差的传力杆进行拉拔试验,发现不同表面处理方式中喷塑处理可以最大可能性的满足传力杆的设置要求,同时发现传力杆角度的偏差是造成水泥混凝土路面接缝两侧50cm范围内出现裂缝的主要原因;通过弯曲疲劳试验,评价了不同水平安装误差条件下(0°、5°、10°、15°)的接缝传荷能力衰减...

| Abstract: | The pull-out test on dowel bar was performed to compare the influence of different treatment methods and deviation of layout on it.It is found that the dowel bar sprayed by plastic can better meet the demand of setting the dowel bar in transverse joints of the concrete pavement,and the reason for cracks appeared in 50 cm range of the joints is the deflection of the dowel bar.Then the bending fatigue test was performed to valuate the degradation regularity of the load transfer capacity of the joints with dif... |
