摘　　要：本文以桐子林水电站二期上游围堰左堰肩处覆盖层灌浆工程为例,对深厚覆盖层灌浆试验展开了研究,通过试验结果分析,确定了一套科学、高效的施工工艺,保证了施工方案满足工程质量和进度的要求,为厂房基坑提供了干地施工条件。The overburden layer grouting project of Tongzilin Hydropower Station stage II upstream cofferdam left dam shoulder is adopted as an example in the paper.The grouting test of the overburden layer is studied.The test results show that a set of scientific and efficient construction technology is determined,thereby ensuring that the construction plan can meet the requirements of the project quality and schedule,and providing factory building foundation pit construction with dry land construction conditions.
