摘　　要：小溶江水利枢纽大坝在施工过程中,因外界气温发生骤降,坝体内外温差过大而在溢流坝段产生温度裂缝,通过采用缝口凿槽嵌缝与内部化学灌浆相结合的措施进行处理后,裂缝部位混凝土的各项指标均能满足设计要求,有效保证了大坝混凝土的质量和安全。In the course of main dam construction of Xiaorongjiang Hydraulic Complex, temperature cracks occurred at the overflow dam segment due to sudden drop of external temperature and too large temperature difference between internal dam body and external air. After cracks were repaired by surface caulking chisel groove and internal chemical grouting, all indexes of concrete at the cracked positions conform to design requirements, which effectively ensure the quality and safety of main dam.
