摘要
Abstract
To address the issues of interference with concrete placement and construction difficulties on conventional blanket-covered consolidation grouting,this study takes the Ulast Reservoir Dam in Xinjiang as a case example.Through field production tests and analysis,a set of non-blanket consolidation grouting techniques suitable for dam foundations is proposed.The grouting effectiveness of the complete non-blanket consolidation grouting system is evaluated by combining acoustic wave velocity testing with water pressure tests.The results indicate that the application of the non-blanket consolidation grouting technique increases shallow-layer grouting pressure,improves grouting operation efficiency,and reduces the risk of uplift.The findings of this study can serve as a ref erence for consolidation grouting construction in dam foundations of similar engineering projects.关键词
