Research on the bearing capability of the middle tower caisson foundation of Taizhou bridge

摘要

An caisson was adopted for the middle tower foundation of Taizhou Bridge. The shallow foundationrncalculation formula commonly used by chinese designer is not applicable for the middle towerrnfoundation located above the 200-meter overlying deposit in the water. Model test and 3Drnnumerical simulation analysis are simultaneously conducted for Taizhou Bridge, to obtain thernfoundation soil bearing capacity of the open caisson foundation of the middle tower and ensure thernstructural safety and stability.
