Application of Leveling Across Large Water Area in Foundation Treatment Monitoring

Leveling precision and efficiency directly influences coastal engineering progress,quality and cost.Since leveling route across large water area is longer,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.
