摘　　要：在混凝土结构裂缝中,长墙裂缝是经常出现的工程质量问题。北京某重点工程地下室墙体施工中,针对单次浇筑长度达50~60m易产生贯通裂缝的问题,采取优选原材料,调整配合比,控制混凝土温度等措施,有效地防止了长墙结构裂缝的产生。Among concrete structure cracks, long wall crack is a common engineering quality problem. During basement wall construction of a key project in Beijing, considering that crack may appear if concrete is cast for 50-60m at a single time, various measures were adopted, such as strictly selecting raw material, optimizing mix proportion and controlling concrete temperature, etc., to effectively prevent the generation of long wall structural crack.
