| 中文摘要:锦屏一级水电站大坝由于基础层混凝土仓面面积大，温控要求严格、间歇期短，固结灌浆施工与坝体混凝土温控存在较大矛盾，主要采取无盖重固结灌浆加有盖重补强固结灌浆及引管的方式进行。主要就无盖重固结灌浆主要存在问题进行了分析和探讨。 |

| Abstract:In Jinping 1 hydropower station, because of large concrete surface of dam foundation, strict temperature control, short construction interval and the contradiction between consolidation grouting and concrete temperature control, both consolidation grouting without concrete covering and reinforced consolidation grouting with concrete covering were adopted. The paper analyzed and discussed the main problems of consolidation grouting without concrete covering. |
