| Abstract: | The article introduces the design and construction gist of double-curve tunnel.The double-curve tunnel is designed on the loading structure process.The article introduces the use of intelligent optimization system,and calculates the practical arch and lining thickness not only satisfying the security coefficient requirements,but also being economic and reliable.The arch optimization and the five-step security construction ensure the joint bearing of surrounding rock and lining,prevent common faults of tunnel,improve the engineering construction quality and decrease the engineering accidents. |
