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。
小溶江水利樞紐大壩在施工過程中,因外界氣溫髮生驟降,壩體內外溫差過大而在溢流壩段產生溫度裂縫,通過採用縫口鑿槽嵌縫與內部化學灌漿相結閤的措施進行處理後,裂縫部位混凝土的各項指標均能滿足設計要求,有效保證瞭大壩混凝土的質量和安全。

In the course of main dam construction of Xiaorongjiang Hydraulic Complex, temperature cracks oc-curred 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 inter-nal chemical grouting, all indexes of concrete at the cracked positions conform to design requirements, which effec-tively ensure the quality and safety of main dam.
