摘要
水准测量的精度和效率直接关系到港口及海岸工程的进度、质量和成本,由于跨大面积水域的测量路线较长,如果观测时前、后视线不相等就会产生较大的测量误差,采用跨河水准测量的方法可以较好地解决这一问题。结合某吹填区地基处理工程监测工作的实践,重点介绍跨大面积水域进行水准测量的方法和步骤,可供类似工程参考。
Leveling precision and efficiency directly cost. Since leveling route across large water area is longer, influences coastal engineering progress, quality and serious leveling error may be caused by the inequality of forward and back sightlines during observation. Leveling-across-river method can be used to solve it well. By combining with foundation treatment monitoring practice in one specific hydraulic fill region, leveling method and process across large water area are introduced in detail, which will provide references for similar projects.
