摘　　要：为提升巷道贯通测量的精度,通过实验模拟,提出前后视三角高程测量和陀螺定向技术相结合的测量手段。其中,前后视三角高程测量能够有效避免三角高程测量存在的误差影响。经3组测量方案对比得到:方案三中的高程贯通精度由0.323 m提升至0.150 m,平面贯通精度由0.47 m提升至0.35 m,测量精度提升显著,进一步验证了这2种测量技术相结合的有效性。To improve the accuracy of tunnel penetration measurement,a measurement method combining front and anteroposterior triangulation elevation survey and gyro-orientation technique is proposed through experimental simulation.Among them,anteroposterior triangulation elevation survey can effectively avoid the influence of errors in triangulation.After comparing three measurement schemes,it was found that the elevation penetration accuracy in scheme three was increased from 0.323 m to 0.150 m,and the plane penetration accuracy was increased from 0.47 m to 0.35 m,indicating a significant improvement in measurement accuracy.This further verifies the effectiveness of combining these two measurement techniques.
