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 didnt 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 cons
