摘　　要：传统的水准式光电测距方法存在着理论上的缺陷,这种缺陷导致了测量精度的降低。从球面几何学的原理出发,探讨了水准式光电测距三角高程测量的原理,推导出了光电测距三角高程测量的严密计算公式,给出了水准式光电测距三角高程测量的实用计算公式。Some theoretical shortcomings exist in the traditional method of EDM trigonometric leveling of leveling type. This theoretical shortcomings resulted in lower of the surveying precision of EDM trigonometric leveling of leveling type . According to the principle of the spherical geometry, this paper approaches the principle of the EDM trigonometric leveling of leveling type. It gives accurate calculation formula of the EDM trigonometric leveling. Also it gives practical calculation formulas of the EDM trigonometric leveling of leveling type.
