| 摘 要： | 沉管在海底的位置靠露在水上的测量棱镜塔目标位置反求，为及时知道水下对接数据，调整施工，要求计算机实时通讯，同步观测棱镜目标，实时显示水底管段的位置特征。结合嘉兴电厂海底隧道工程，介绍了沉管隧道对接的测量理论和实施措施。

| Abstract: | The submerged tube section can not be observed directly,whereas its location could be known by means of the prism tower.In order to get the data of the joint part of the tubes in time,the instruments must be connected to the comuter.In this way,the observation is obtained and processed with the computer on time,and the location data of the submerged tube section is illustrated timely.Combining with the undersea tunnel engineering in Jiaxing power plant,the measurement theory and method for submerged tubes to be joined together undersea are present. |
