摘　　要：分析了井下三角高程测量误差的主要影响因素,提出了一种把钢尺丈量的误差当作参数放入观测方程,并采取上述前后视观测和不挪动脚架测量的方式进行三角高程测量,经理论和实践验证,在一定程度上能达到常规水准测量的四等要求。The author analyses the main factors of underground trigonometric leveling error,provides that we may put the error of steel ruler measurement as parameter into the observation equation,and carries out trigonometric leveling getting the way of the above-mentioned fore and back observation and the measurement method that it is not moving.After verification of theory and practice,to a certain extent,it is can achieve the standards of the four requirements of routine leveling survey.
