摘要
隧道结构应在设计使用年限内满足结构的安全性、适用性和耐久性要求,目前隧道结构的耐久性设计方法还不够完善。隧道结构的耐久性不能仅仅按照提高材料的质量和加大结构厚度等构造要求进行设计,还应该采用多道设防的设计理念,结合结构安全性设计,综合考虑隧道结构在环境作用下的耐久性。文章结合隧道结构的耐久性,对复合式衬砌隧道结构设计中的几个问题进行了分析与探讨,并提出了解决方案。
Tunnel structures should satisfy the requirements for structural safety,adaptability,and durability for the design working life.Currently,the method of durability design of tunnel structures is not perfect.Durability of tunnel structures can not just be designed in accordance with the structural requirements for the quality of materials and thickness of the structure-it should also be supported by consideration of alternative design ideas,taking into account environmental influences on the durability of the tunnel structure as well as the structural safety of the design.This paper analyzes and discusses several issues regarding structural design of composite tunnel linings incorporating the durability of the tunnel structure and offers some concrete solutions.
