垂线观测精度对引张线观测精度的影响分析

Influence Analysis of Observation Accuracy with Vertical Line on Tension Wire Alignment

基于误差传递原理,分析了垂线作为引张线工作基点时垂线观测精度对引张线最终水平位移观测精度的影响。实例结果表明,垂线观测精度对引张线最终水平位移观测精度有明显影响,且对引张线两边测点的影响程度大于中间测点;采用垂线法和引张线法联合配套观测水平位移时,引张线各测点最终水平位移的理论观测精度不同。

Based on error transfer principle,the influence of vertical line observation accuracy on horizontal displacement with tension wire alignment is analyzed by vertical line as a base point of wire alignment.The results show that the observation accuracy of vertical line makes significant influence on wire alignment,and the influence is stronger on the measuring points of both sides than on the intermediate points.It is different for the theoretic observation accuracy of wire alignment each point with jointly m...
