Article Preview

Abstract:

This paper summarizes the design of reinforced concrete structure and its enclosure for a subaqueous tunnel used to cross a river in urban highway line. The tunnel mainly consists of open-cut section on river bank and cut-cover section under river bed. Their structure and enclosure are both illustrated in the paper according to site geology and general layout of urban highway line. The use of rotary bored pile and soil mixing wall to preserve the stability of open-cut foundation pit are summarized in the paper.
