摘　　要：根据衡阳某高层建筑的实际经验,提出了防治基础大体积泵送混凝土早期裂缝应采取控制原材料与配合比、分区分段施工、优化配筋、设隔离层、加强温度控制等施工措施,可达到较好效果,为同类工程施工积累经验。Combined with working experiences of one high-rise building in Hengyang construction measures adopted in mass pump concrete construction of foundation works to prevent the production of early cracks are presented and discussed, which includes raw material and mix proportion control, section construction, reinforcement optimization, setting isolation layer, strengthening temperature control and so on. Practice receives good effects, which accumulate good construction experiences for similar works.
