Abstract: The Shiziyang tunnel is in passenger dedicated rail line connecting Guangzhou, Shenzhen and Hong Kong. It will be the longest underwater tunnel and have the highest technical level in China. This article describes the tunnel’s design and construction schemes, analyzes and summarizes the characteristics of this tunnel, in terms of its geological and hydro geological formations; and defines the strata graphic classification. According to sub-formation and characteristics of the tunnel, this article discusses the problems that may arise in the construction of the tunnel in sub-strata, declares the key points in technology of shield tunneling in three major aspects: soft ground, the upper-soft and lower-hard mixed ground and hard rock (medium hard rock) ground.
