    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.
