摘要
针对贯通测量中采用规程参数进行误差预计不能完全反映实际测量误差的问题,提出了采用测量实际统计参数对贯通测量误差进行预计,并在实际工程中将用统计参数和规程参数预计的误差与实际测量偏差值进行对比,得出:在贯通测量误差预计中,采用实际统计参数比用规程参数进行贯通测量误差预计更能提高测量误差预计精度。
In order to solve the problem that the actual errors can not be represented clearly in the tunnel-crossing measurement using procedure parameters for error prediction. The error predicted by statistics parameters and procedure parameters are compared with the windage in practical survey. The result shows that using statistics parameters for error prediction can provide more accurate precision.
