Analysis on the Construction Safety of Hongkong-Zhuhai-Macao Cross-sea Bridge

Abstract

With the continuous development of highway and bridge construction in China, the number of cross-sea projects is increasing. The large scale and bad construction environment of cross-sea bridge project put forward a severe test to the construction safety. At present, although China has completed a large number of cross-sea projects, the analysis of construction safety is still insufficient. As a large cross-sea bridge, the Hongkong-Zhuhai-Macao Bridge is representative with harsh construction environment, complex geological structure and high environmental safety requirements. Therefore, this paper takes the Hongkong-Zhuhai-Macao Bridge as an example to analyze the construction safety. Firstly, the safety of construction platforms in different sea areas are discussed, and then, the construction of bridge substructure under complex geological conditions and natural environment are also displayed. In the face of these harsh construction conditions, the Hongkong-Zhuhai-Macao Bridge has adopted some targeted schemes, which provides a good reference model for the construction safety of other cross-sea projects.
