摘　　要：在平面尺寸较大或形状较为复杂的高层和超高层建筑中,常常通过设置后浇带来减少温度变化、混凝土收缩、地基不均匀沉降等因素对结构带来的不利影响。后浇带可以避免裂缝的产生和控制裂缝的发展,确保结构安全和使用功能。The concrete post - cast belt can be used to abate the ill effects to the structure that are caused by the temperature variation, the concrete shrinkage as well as the fotmdation uneven settlement and soon in thehigh- rise or supper high - rise building whose flat dimensions are large or forms are complex. It also can avoidthe appearance of the concrete fissures and control their development, which can ensure the structure safety and application functions.
