摘　　要：在高海拔或高程变化较大的地区进行工程测量时,为了限制投影变形,一般采用具有抵偿高程面的工程坐标系。本文通过分析工程椭球与国家参考椭球之间的内在联系与差异,推导了工程椭球大地坐标的改正值公式,给出了工程椭球的建立方法及坐标换算方法,从而保证顺利地建立具有抵偿高程面的工程坐标系。In high altitude or elevation changes in the larger area of engineering measurement, in order to limit the projection deformation, use is generally compensated height surface engineering coordinate system. Is deduced in this pa- per, through the analysis of the inherent relationship and difference between engineering ellipsoid and the national refer- ence ellipsoid engineering ellipsoid geodetic coordinate correction value formula and gives the engineering ellipsoid estab- lishment method and the method of coordinate conversion, so as to ensure the smooth established with compensation height surface engineering coordinate system.
