利用ＧＰＳ水准对几个重力场模型计算的大地水准面进行了检验。利用ＷＤＭ９４模型编制了华北地区不同阶次的大地水准面起伏图，讨论了大地水准面起伏和该地区构造横向不均匀性的关系。结果显示：华北地区大地水准面由东向西逐渐降低，总体形态和本区地壳厚度呈镜像关系，且具有明显的分区特征；大地水准面的梯度带和本区３种不同地形的分界带（华北平原，太行山区，鄂尔多斯块体）一致，其中１１５°（Ｅ）分界带和我国东部的主要地壳厚度梯度带一致；大地水准面零等值线的两侧是地震比较集中的地带。
The geoid calculated by several gravitational field models was tested by GPS level. Based on the WDM94 model, different levels of geoid undulations are compiled in North China. The relationship between the geoid undulation and structural lateral inhomogeneity is discussed. The results show that the geoid in North China gradually decreases from east to west, and the overall morphology is mirror image of the crustal thickness in the region with obvious zoning characteristics. The gradient zone of the geoid and the boundary zone of the three different terrain North China Plain, Taihang Mountain and Ordos blocks). The 115 ° (E) boundary zone is consistent with the main crustal thickness gradient zone in the eastern part of China. On both sides of the geoid zero contour line, there are more concentrated earthquakes.
