| Abstract: | Karst geomorphy has a wide coverage in China.There is a high possibility for the construction of highway tunnel cut across karst caves. Taking an example, this paper proves the safety and possibility of the bridge construction technology for highway tunnel cut across karst caves. It affirms some advantage of the construction ,such as its high quality, right schedule, and little disturbance to tunnel. The paper also discusses all methods in each construction step and matters needing attention. |
