| Abstract: | The construction techniques and methods of borehole in the sea bridge construction were summarized and analyzed to acquire the pile foundation pore-forming construction technique of sea bridge,which was applicable,and research on the question about pouring concrete over water was carried out.The result indicates that the proportion of circulating mud should be between 1.04 and 1.17 g·cm~（-3）;the viscosity should be between 20 and 25 s;the thickness of mud layer should be less than 2 mm;the sand content should be less than 3%.The research achievement can be referred to by similar projects. |
