【摘要】 超长隧洞施工测量属于超规范作业,为保证超长隧洞贯通,必须对超长隧洞施工测量进行研究。对隧洞施工测量中洞口控制网布设、数据处理及其误差对贯通的影响与洞内基本控制网的布设、平差及检核方法等若干问题进行了研究,所得成果已运用于引黄入晋工程中的南干5#和7#超长隧洞施工测量中,确保了两超长隧洞的顺利贯通。更多还原

【Abstract】 The construction survey of extremely long tunnel is a work beyond the standards. The especial problem of the control survey of extremely long tunnel must be researched in order to ensure two parts of the tunnel linkingup. This paper discusses the control network establishment, the data calculation, the influence of the control survey on the precision of the lateral linking-up and the adjustment and the checking way of traverse survey inside the tunnel. The conclusions have been used in the NO.5 tunnel and NO.7 tunnel of south main trunk of YINHUANGRUJIN project and ensured the two tunnel linking up successfully. 更多还原
