Research on settlement test and numerical calculation of west artificial island foundation of Hong Kong-Zhuhai-Macao Bridge

ABSTRACT

The artificial island project of the Hong Kong-Zhuhai-Macao Bridge includes the island construction project, the island part at the junction of the island and the tunnel, and the transition section between the island and the tunnel. The bearing capacity and deformation characteristics of the compacted sand pile composite foundation are studied through the load test of underwater compacted sand pile composite foundation, and given the parameters such as pile-soil stress ratio of composite foundation. In addition, the numerical simulation analysis of the three-dimensional foundation model of the West artificial Island was carried out. The parameters were adjusted through back analysis of the calculated results and the measured data, and the adjusted parameters were used to calculate the post-construction settlement of the West artificial Island, which met the design requirements of no more than 50 cm.
