48、后浇带，通过HEA掺量设计混凝土的膨胀量。膨胀加强带间距为40m60m左右，带宽2m，膨胀加强带两侧铺设密孔铁丝网和8150钢筋加固，目的是防止砼流入加强带，膨胀加强带外用普通掺量的补偿收缩混凝土浇筑，混凝土膨胀率约（22.5）10-4，加强带内用大膨胀率混凝土浇筑，混凝土膨胀率约为（2.53.5）10-4，其强度等级比两侧提高5MPa。如此循环下去可连续浇筑100150m超长结构，而不设后浇带，参图1。由于混凝土供应或施工组织原因导致混凝土不能连续浇筑时，可用“间歇式无缝施工法”，详图2，即浇筑至加强带一侧作为施工缝，在下次浇筑混凝土前，把施工缝清理干净，凿去部分保护层，充分润湿混凝土界面，
