| Abstract: | Karst cave in Karst areas has a great impact on the construction of shield tunnel. Before construction, karts cave needs to be filled and parameters of grouting should be chosen so as to ensure the grouting effect. In this paper, the construction process of filling and grouting of karts cave in shield tunnel from Huadu Square to Ma＇ anshan of Guangzhou Rail Line 9 is introduced, including the determination of cave＇ s range, selection of grouting material, con- struction sequence and technical control of grouting and monitoring of grouting effect, which is of great reference signif- icance to similar construction. |
