论文题目：陀螺定向在贯通测量中的应用实例分析 专 业：测绘工程 本 科 生：钟文兵 （签名） 指导教师：朱学军 （签名） 摘 要 隧道或井巷工程测量导线布设的形式因受巷道形状的制约，若单纯采用改变导线布设形式或提高测角次数与精度等方法，往往难以满足工程施工对于测量的精度要求。陀螺经纬仪是测量井下导线边方位角、提高测量精度的重要仪器。尤其是在贯通测量中陀螺经纬仪的应用非常广泛。贯通测量是一项十分重要的测量工作,必须严格按照设计要求进行。巷道贯通后,其接合处的偏差不能超过一定限度,否则就会给采矿工程带来不利影响,甚至造成很大的损失。本文对陀螺经纬仪工作原理介绍，以及陀螺经纬仪在贯通测量中的精度评定。陀螺经纬仪在不同领域的贯通测量工作中运用实例的分析，总结出在贯通测量导线加测陀螺定向边的最佳位置。 关 键 词： 陀螺定向，贯通测量，陀螺经纬仪，精度评定 Subject ：Directional gyro in the measurement through the application of analysis Specialty ：Geodetic engineering Name ：Zhong Wenbing　　　　 （Signature） Instructor：Zhu Xuejun （Signatrue） ABSTRACT Tunnel or shaft engineering measurement wires for the form of roadway, if simple shape by changing arrangement forms or improve wires and precision Angle measurement methods, and often difficult to satisfy the measurement accuracy for engineering construction. Gyro theodolite is measured in wire edge Angle, improve the measuring precision instruments. Especially in the measurement of the photoelectric theodolite gyro breakthrough is used extensively. Through measurement is a very important measurement work, must strictly according to the design requirements. The roadway expedite, its joint deviation cannot exceed a certain limit, otherwise they will be detrimental to the mining project, and even cause great losses. This paper introduces working principle of gyro theodolite, as well as the breakthrough in the measurement of the gyro theodolite accuracy assess. Gyro theodolite in different fields of the measurement of the examples, this paper leads in breakthrough measurement on the edge of the directional gyro adds the best position. Key words: directional gyro; through measurement; gyro theodolite; Accuracy Assessment PAGE 27 目 录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc231813234 1 绪 论 PAGEREF _Toc231813234 \h 1 HYPERLINK \l _Toc231813235 1.1 陀螺定向的研究现状 PAGEREF _Toc231813235 \h 1 HYPERLINK \l
