摘要
本文借助于弹性力学应变分析理论，提出ＧＰＳ网应变强度分析法，建立了对应于椭球微分坐标系的“位移－应变”数学模型，分析了ＧＰＳ模拟网应变强度的分布情况，得出一些有益的结论。
The strain strength analysis method of GPS network and the displacement --deformation mathematicalmodel in the differential ellipsoid coordinate system have been established by using the strain analytical theoryin. the elasticity mechahics. The distribution of the strain strength of the simulation GPS networks have beenanalysed. As a result, the author has obtained some practical conclusions'
