摘要
Taoshuya tunnel is located in the Fengjie-Wushan section of Yu-Yi Freeway, the geological condition is very bad. Large deformation and serious damage happened on the tunnel under construction. Based on correct understanding of dynamic evolution mechanism of the surrounding rocks, a new reinvention and reinforcement program was adopted from the viewpoint of controlling surrounding rocks. Those parts include large deformation and serious failure was repaired successfully. The construction of the tunnel through the bad surrounding rocks benefited from the research results. The Taoshuya tunnel is finished safely and successfully at last.
