摘要
Abstract
In this study,two representative test areas on the left bank were selected for consolidation grouting tests.Analyses were conducted from perspectives such as grouting methods,unit injection rate,water permea-bility before and after grouting,sonic wave testing,and rock mass deformation modulus testing.The results in-dicate that the strength,integrity,and uniformity of various rock mass grades in both test areas were signifi-cantly improved after grouting.Among them,the weakly weathered and weakly unloaded Class Ⅲ2 rock mass and the deeply unloaded Class Ⅲ2s rock mass exhibited the most notable improvements in quality.The expec-ted objectives of the consolidation grouting tests were achieved,and essential parameters for the grouting de-sign were obtained,providing critical guidance for subsequent engineering construction.关键词
