摘 要
隧道工程测量是在隧道工程的规划、勘测设计、施工建造和运营管理的各个阶段进行的测量。本文主要阐述施工建造阶段的测量工作。
峪园隧道全长2714m,单洞双向通行,是进入张家界森林公园的必经之地,地理位置十分重要。该隧道所在地形比较复杂,属于一个多山的地区。而且大部分属于喀斯特地貌,为保证隧道能按规定的精度正确贯通,根据隧道施工要求的精度和施工顺序进行相应的测量,首先根据隧道线路的形状和主洞口、辅助洞口、转折点的位置进行洞外施工控制网和洞口控制网的布没及施测,再进行中线进洞关系的计算及测量,随着隧道向前延伸而阶段性地将洞内基本控制网向前延伸,并不断进行施工控制导线的布测和中线的施工放样,保证不同工作面之间以预定的精度贯通,贯通后进行实际贯通误差的测定和线路中线的调整,施工过程中进行隧道纵横断面测量和相关建筑物的放样。 关键词:隧道测量,控制网,贯通预计

Abstract
Tunnel engineering survey are made in the tunnelling works planning, investigation, design, construction and operation of the various phases of the measurement. This article focuses on construction surveying in the construction stage.
Hanguguan tunnel is the Zhengzhou-Xian a large tunnel on passenger dedicated line, is an important project on the line as a whole. Tunnel length of 7840m. The location of the tunnel complex, is a mountainous region. And most of them located on the loess plateau with secondary accumulation of Yellow River terraces, height 370~590m relative height difference almost 220m. Tunnel terrain is a large, natural cross slope of 10~35 °. For guarantee tunnel can by provides of precision correctly through, to requirements: according to tunnel construction requirements of precision and construction order for corresponding of measurement, first according to tunnel line of shape and main entrance, and secondary entrance, and turning point of location for hole outside construction control network and entrance control network of cloth didn't and the Shi measuring, again for middle into hole relationship of calculation and the measurement, with tunnel forward extends and stage to will hole within basic control network forward extends, And construction control for continuous measurement of the wire and the centerline of the construction survey, guidance and assurance between different faces to the intended accuracy through through after the actual breakthrough error of measurement and adjustment of Central line, aspect of tunnel section measurement in construction and building layout.
Key words: measurement of tunnel, passenger, control networks, linking is expe
