STUDY ON DURABILITY OF LINING CONCRETE OF SUBSEA TUNNEL AFTER FIRE

摘要：

Along with the development of subsea tunnel and traffic, fire often takes place. So far, lots of researches have been carried out on the safety and suitability of lining concrete structures. However, for the service environment of subsea tunnel is so serious, harm of fire to the durability of lining concrete is more significant. In this paper, experimental studies on the durability of lining concrete of Jiaozhou bay subsea tunnel after fire is carried out considering the characteristics of the service environment. Results show that temperature affects greatly on the durability of concrete. When it is up to 200C to 300C, deterioration of the durability of concrete is obvious. And chloride penetration resistance will be degraded quickly.
