摘　　要：规范规定建立或选择平面坐标系统的前提条件是测区内投影所引起的长度变形不大于25 mm/km。某测区公路工程施工控制网采用国家坐标系不能满足这一要求,为减小高斯投影长度变形所带来的影响,本研究选用膨胀椭球与重心坐标不变法建立工程抵偿坐标系,并基于C#语言进行抵偿坐标系最佳抵偿面选取软件设计。研究结果表明,该计算方法严密、可靠,软件计算结果快速准确,可以实现抵偿坐标计算的自动化处理,能够满足规范要求,可直接应用于工程生产。It is stipulated that the precondition of establishing or selecting the planimetric coordinate system is that the length deformation caused by the projection in the survey area is not more than 25mm/km.The national coordinate system adopted by the highway engineering construction control network in a survey area cannot meet this requirement.In order to reduce the influence caused by the deformation of Gaussian projection length,this study chooses the method of expanding ellipsoid and barycentric coordinate invariance to establish the engineering compensation coordinate system,and designs the software for selecting the best compensation surface of the compensation coordinate system based on C#language.The research results show that the calculation method is rigorous and reliable,the software calculation results are fast and accurate,and the automatic processing of compensation coordinate calculation can be realized,which can meet the specification requirements and can be directly applied to engineering production.
