摘要
本文介绍了利用电子计算机模拟的随机数所构成的模拟观测值,采用导线计算公式直接推出贯通点偏差的贯通误差预计方法。该方法所得偏差比传统误差预计方法所得预计值更为接近于实际贯通偏差.
This paper presents a method of predicting heading-through errors in which the disorepancies for heading-through points are derived by use of random data produced by computer simulation and according to related traverse form- ulae. This method gives results closer to praticle heading-through discrepa- ncies than the conventional method
