| Abstract: | In accordance with fracturing grouting consolidation in some tunnel of Nanjing subway north-south line, the function and mechanism of grouting and its influence parameters are analyzed, and the material and ratio of cementing paste as well as its effects are discussed. The in-situ experiment results demonstrate that this technology is suitable with notable effect. |
