Investigation and Statistical Analysis of Durability of Concrete Tunnels in Southeast Coastal Areas of China
Durability of reinforced concrete (R. C.) is a worldwide concern nowadays because R. C. structures will deteriorate and damage under natural environment and long-term usage. To have an overall knowledge of the durability of concrete tunnels in southeast coastal areas of China, 13 sample tunnels in 6 cities of Zhejiang Province were investigated. The main diseases, disease spot and the relationship between the degree of disease and service time of tunnel were statistically analyzed. Results indicate that the main disease of the tunnels was water leakage, reaching 77％, more than 90％ of the diseases occurred in the lining, and degradation of tunnels varied significantly in degree and style with environmental conditions of different areas. Finally, some preliminary suggestions on durability design of coastal tunnels are proposed.
