轴线不平行于控制网的基坑控制点坐标值的简便计算方法

THE SIMPLE CALCULATION METHOD OF THE VALUE OF PIT CONTROL POINT COORDINATES WITH THE AXIS NOT BEING PARALLEL TO THE CONTROL NETWORK

在某工程测量工作中发现,对于轴线平行于测量控制网的基坑,其控制点的放样一般测量人员都能熟练掌握。而对于轴线不平行于测量控制网的基坑,其控制点的放样则难度较大。经过实践,提出了解决这个问题的简便方法。

During the survey work of a project,it was found that for the pit with the axis being parallel to the survey control network,whose control point loft,can be mastered in general by surveyors.Whereas for the pit with the axis not being parallel to the measurement control network,whose control point loft is more difficult.After practice,it has been found out an easy way to solve such problems.
