Abstract:Research purposes : Immersed Tunnel Technology is an advanced subaqueous tunneling method,which need take structure, construction scheme, hydrogeological parameter, working factors into account. With the construction of Shenjiamengang immersed tunnel project, several of key technologies of design method were analyzed and researched to guide the design.
Research conclusions: The research , such as tunnel hydrological conditions, immersed structure, the water resistance of immersed sinking, calculation of GINA joint selection, project design measures durability, etc.,solved the several key tunnel technical problems. With the help of research, the design of Shenjiamengang immersed tunnel was successfully completed. The reference experience of channel immersed tunnel design was accumulated.
