| 摘 要： | 水准测量是确定公路工程地面点高程的方法之一,是高程测量中精度较高常用方法。实施过程中,需要几个人合作才能完成。误差允许范围内的精度由于仪器和人为的影响而不容易控制,而且易出现隐蔽性错误。如果不能及早发现基础资料是错误的,水准点高程不正确,直接影响路线纵断面设计和施工。本文就水准测量的工作原理、误差来源,误差控制等几方面结合工程实例进行分析。

THE ERROR SOURCE AND CONTROL OF LEVELING SURVEY IN HIGHWAY ENGINEERING |
| |
| Abstract: | As one of methods of determining ground elevation in highway engineering, leveling survey is a High Accuracy and common method of elevation measure, and is completed through cooperation. Accuracy within the range of admissible error is uneasily controlled and usually produces hidden error because of the influence of instrument and human factors. If the error is not found and corrected timely, wrong basic data will lead to wrong elevation of bench mark, and affect on directly of profile design and road construction. This paper chiefly analyzes principle, error source and control of leveling survey combining practical projects. |
