| 摘 要： | 传统的水下地形测量,系垂直于岸线设置断面,船按既定断面航行;测水深时,船必须处于静止状态。 改进后的渔港水下地形测量方法,是采用以锚标设置的平行于岸线的水上断面,并且利用沿断面航行中之动船测定水深。这样既提高一倍的工效,又保证了测量的精度。

| Abstract: | In the topography survey under water, it is the tradition way of setting the sections that take advantage of vertical section to shoreline. In the way, the direction of survey boat must move along the section to be determined. The boat must be rested in surveying depth of water. The new way of surveying topography under water of fish ports in this paper that the section parallel to shoreline was adopted and set the mark with anchor. In the new way, depth of water can be surveyed using of the moving boat. The new way not only increase in efficiency by 2 times, but also guarantee the accuracy of survey. |
