摘　　要：针对桥梁GPS高程控制网两岸高程基准的不一致性问题 ,采用了外推法、解系统差参数、高程异常差拟合三种方法对GPS高程进行处理 ,对各种方法进行了分析和比较 ,并采用某线路控制网模拟桥梁GPS高程控制网进行实例分析 。Three handling methods are applied on differ in consistency of both sides of bridge of GPS height network. The methods are analysed and compared by means of the example that a route control network is simulated bridge GPS height network. An optimal schema of applying height anomaly difference fitting is gotten.
