摘　　要：针对现有闭(附)合三角高程路线平差方法的不足,运用条件平差原理,以三角高差为观测值,在依据误差理论合理确定权的基础上,推导出了严密的高差改正数计算式与高程中误差计算式,平差方法合理、正确、可靠,计算过程简单,易于理解。Based on the defects of the existing route adjustment methods for closed(attached) triangulated height, and combined with the principle of conditional adjustment, precise height difference correction calculation equations and height error calculation equations were derived based on the reasonable assured weight in the error theory, with the triangulated height difference as the observed value. The adjustment methods were reasonable, correct and reliable, and the computation process is simple and easily understandable.
