| 摘 要： | 本文使用三种地形调整方法对某地调整大地水准面进行了计算,三种方法分别是:Airy-Heiskanen型地形均衡方法(TIC)、剩余地形改正万法RTM、自由空气改正。结果表明,RTM方法较优、自由空气改正次之,而地形均衡方法最差。

| Abstract: | Three topographic regulation methods are researed and implemented for the evaluation of regulated geoid in the interest area. The methods are: 1) the Airy-Heiskanen topographic-isostatic compensation (TIC) method. 2) the residual terrain model reduction (RTM) and 3) the free air condensation method. The investigation in the paper showes that the accuracy of RTM is highest, the that of the free air condensation higher and the that of TIC lowest. |
