摘要
本文从分析帷幕灌浆设计入手，着重介绍了帷幕灌浆施工工艺和质量检查；通过测试数据对灌浆效果进行了评价分析，认为通过大坝中热水泥高压灌浆，河床坝基幕体已基本形成。
Construction techniques for high pressure curtain grouting with superfine cement are described in detail. Grouting effects are analyzed with test data. The results show that fine cracks have been filled in rock mass after high pressure curtain grouting with superfine cement were applied. Exceptional cases emerged in high pressure curtain grouting are approached.
