Design and Construction Gist of Double-curve Tunnel

该文介绍了双曲隧道的设计与施工要点。双曲隧道按荷载结构法设计,采用智能优化系统,计算出既符合安全系数要求,又经济可靠的实用拱形和衬砌厚度;通过拱形优化,按照五步安全施工,确保围岩、衬砌共同承载,预防隧道常见病害,提高工程施工质量,减少工程事故。

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.
