疏港航道大桥基桩导线测量放样的控制

Control of Orientation Measurement Setting of Bridge Base Pile in Shu Gang Channel

测量放样的控制直接影响工程施工放样的准确性。结合大丰港疏港航道大桥基桩测量放样工作,采用导线测量确定各加密点的坐标和高程的具体测设过程。导线测量结果构成了本项目施工测量控制网,确保了基桩施工放样的精确性。

Control of staking out directly affects the accuracy of the construction setting. Combining the mea- surement of bridge base pile in Shu Gang channel, Da Feng port, it is suggested to adopt the orientation measurement to determine the encrypted coordinates of points and the elevation. The result of the orientation measurement consti- tutes the control net of the project construction measurement, and ensures the accuracy of the foundation construc- tion setting.
