| Abstract: | The survey control items of immersed tunnel gravel bed of Hongkong-Zhuhai-Macao Bridge are discussed firstly.Aiming at the high elevation accuracy of the gravel bed under sea water,this paper verifies the accuracy and reliability of sounding data through comparison and analysis of multibeam sounding data.The point and plan combined survey method based on the special designed single beam sounding and the multibeam sounding are put forward.And the drawing measuring method for the structure size measurement of the deep grooves under the deep seawater is proposed based on the massive and high precision data.These methods implement the immersed tube tunnel gravel basic comprehensive quality control and provide the basis for the quick decisions of socket installation. |
