To roll with the famous Qiantang tidal bore and to reduce the construction risks under difficult hydrologic conditions, the substructure foundation design for the southern and northern bridge approaches called for the elimination of the traditional pile cap and the use of a single pile and flexible column type with a large pile diameter of 3.8m ...
