摘要
导致新铺旧桥桥面砼铺装层在靠近新旧桥面接缝一定范围内产生纵向裂缝的主要原因是:车辆荷载对桥面的冲击力所产生的振动和车辆荷载引起的新旧桥面板的竖向变形差。
The main cause of lognitudinal crack in some range of new and old bridge seam at new concrete layer on old bridge surface,is the vibration engendered by vehicle loading wallop and vertical distortion difference between new and old bridge faceplate caused by vehicle loading either.
