水下高程测量新方法初探

传统的水下构筑物高程测量方法是使用水准仪或GPS配合尺杆将绝对高程传递到水下待测点。当工程距岸较远、水深增大时，测深的误差显著增大、测量的工作时间大大延长、水上测量平台的搭建成本显著增加。为此开发了利用水压传感器测深的新方法，对于所面临的波浪影响问题进行了专题研究。从波浪理论出发，对水下固定点压强波动振幅同表面波高及固定点水深的函数关系进行了推导，得出了利用参考点和被测点压强波动振幅实测值计算被测点水深的方法，可作为实用阶段测量系统研究开发的基础和途径之一。

Preliminary Research on New Method of Underwater Absolute Elevation Survey

Traditional method to measure the elevation of underwater structures is to transmit the absolute elevation from the land-based control points to the underwater points to be measured by using leveling instrument or GPS together with leveling rod.When a project is far away from the coast with increased water depth,the sounding error increases significantly,working hours of surveying extend greatly,and the expenditure in construction of platforms for underwater surveys increases significantly.Therefore,a new m...
