The Impact Analysis of Grouting Effects to the Settlement of Subway Tunnel Construction
For subway tunnels such as Nanjing Metro II excavated by mining method, one of the most important reinforcement methods for preventing surface settlements is the grouting method. There are many soft and weak surrounding rocks and abundant groundwater in the metro section, so grouting has become a major method in reinforcing the fragmented rocks and soil. But bad grouting support caused by fluid loss in soil and rock often allows uncontrollable settlement. In order to analyze the differences in grouting techniques, combined with the actual excavation process and the contrast of different means of settlement control in a complex section of Metro II, this paper adopts the numerical simulation method of FLAC3D to demonstrate that strict management and proper methods can create good and dependable reinforcement of the unstable surrounding materials.
