Research on Key Technology of Super Long Pile Foundation Construction in Offshore Area

The Hongkong-Zhuhai-Macao Bridge has been under construction for more than 20 years from planning to completion.The construction process has been difficult and has attracted worldwide attention.The geological environment of deep water pile foundation of the river-sea direct ship channel bridge of Hongkong-Zhuhai-Macao Bridge is complex and its construction is difficult.There are many difficulties in the construction process.By predicting in advance,the relevant engineers analyze the emphases and difficulties of construction process,and prepare the key technical essentials by combining with the relative construction technical requirements,and at the same time,solve the technical difficulties in the construction process.The good effects are achieved in the implementation of pile foundation and the engineering construction of pile foundation is ensured to complete smoothly.In the type of pile foundation construction in deep sea waters,the related technologies have been innovated and have been successfully applied in the implementation process.
