| Abstract: | Taking a typical tunnel in southwest Karst area as an example, subsection grouting are carried out with different pass traversing model. The change of filling physical properties before and after grouting, routing pressure, P-Q-t curves are analyzed, the deformation conditions of tunnel arch before and after grouting are also analyzed by numerical software. Finally the key points of grouting reinforcement technology for highway tunnel pass through large filling karst cave are given. |
