摘　　要：针对在已知水准点距离较远且联测有困难的情况下,提出了运用GPS高程平面拟合的方法来进行高程传递,通过理论阐述,结合具体工程实例,得出了在控制点分布和网形结构合理的情况下,GPS高程平面拟合法可以代替四等水准测量,并对以后的类似工程提供了参考和建议。The control points are scarce or conjunction level difficult circumstances, was studied by using the method of GPS elevation plane fitting instead of four leveling, through theory and practice, the methods are described, engineering application using the geometric leveling data collected and measured data obtained on the GPS control network as the known data, elevation fitting through the net shaped structure different, carries on the analysis to the result of comparison, conclusion and suggestion.
