摘　　要：在公式推导的基础上,估计各种误差的影响,研究了近距离内全站仪三角高程测量的精度,并通过实际测量和水准结果的比对进行验证,指出垂直角测量误差是影响高程精度的重要因素,对于精密工程测量中的广泛应用的全站仪三维测量具有参考意义。On the basis of formula deduction, the effect of error is estimated and the accuracy of trigonometric leveling by Total Station in short distance is investigated and validated by the contrast between results from precise trigonometric leveling and leveling. The paper draws a conclusion that vertical angle error can affect the accuracy of height seriously, which can be a reference by the widely used 3D measurement by Total Station in precise engineering practices.
