| Abstract: | In relation to the diseases arose out of the monolithic roadbed of Xiaozongxi Tunnel, the genesis was analyzed by use of the results of GPR detection and laboratory test. According to the comprehensive restriction on maintenance gap for tunnel in operation, the diseases in the monolithic roadbed was treated by reinforced TGRM cement-based special grouting material and the grouting technology. The practice has proved that the expected goal is reached. |
