摘要
针对控制测量中因高斯投影变形引起的起算控制点之间长度变形值超出规范要求的问题,总结出包括中央子午线换带法、投影面重新选择法和尺度强制约束法在内3种解决该问题的方法,其中重点推荐尺度强制约束法,以期为类似的工程测量提供参考。
As for Gauss projection length deformation among the starting control points going beyond the relevant specification requirement in control survey, three methods are summarized to resolve the above problem, i.e. the central meridian transition, projection side re-choosing method and forcible tie by dimension. The last one is especially recommended, which may provide the reference for the similar engineering survey.
