摘　　要：结合实例对大体积结构的裂缝产生原因,提出利用膨胀混凝土防水,抗裂.并从施工工艺及技术措施上进行分析,探讨其中最优方案,达到无缝施工的目的.When bulky structure pours concrete , cracks puzzle it. The treatise links up with the example to raise a point of resolvent about the cause of prouducing cracks in construction. To utilize intumescent concrete prevents structure from making water and resist crazing. By analyzing construction jawboning and technic measures, we discussed optimization project for construction without cracks, in this paper.
