摘　　要：陆上勘查孔位海拔高程的测量工作多采用水准高程传递的方法。海上钻探孔位的海拔高程,由于海洋条件限制,此方法并不适合。为了满足近海工程勘察中测量孔位高程的实际需要,本文采用实时动态差分全球定位系统(GPS-RTK)技术和测深技术,组成RTK和测深仪联合作业系统来测量勘查孔位的标高,在实际近海海洋勘查中取得了良好效果,以便促进RTK技术在海洋工程建设中的应用。The leveling elevation transfer method is usually used for measuring the elevation of land exploratory borehole, but this method is inapplicable to the measurement of elevation of offshore borehole due to the limitation of marine conditions. In order to meet the requirements for measuring the elevation of offshore borehole, the combined real time kinematic global positioning system （RTK-GPS） and sounding technology is used to measure the elevation of offshore borehole, and good results have been obtained in applying the combined technology to offshore engineering investigation, which will promote the application of RTK technology in constructing the marine engineering.
