【摘要】：针对隧道洞内控制测量目前普遍采用的支导线和双导线网两类方法的不足,研究并提出了一种长大隧道洞内虚拟双导线测量技术方案,采用一条真实存在的支导线和一条内业虚构的虚拟支导线组合成虚拟双导线测量方案,使其既具有常规的支导线简单快捷优点,又具有常规双导线多余观测形成闭合条件的特点,适应现场复杂的测量环境,突破多因素对选点埋桩、测量的限制,在节省费用的同时提高了测量作业效率。
[Abstract]:Aiming at the deficiency of two kinds of methods, branch wire and double wire network, which are widely used in tunnel control survey, this paper studies and puts forward a kind of virtual double traverse measurement scheme in long tunnel tunnel.By combining a real branch wire with a fictitious virtual branch wire in the industry to form a virtual double traverse measurement scheme, it has the advantages of simple and fast conventional branch conductor.It also has the characteristics that the superfluous observation of conventional double conductors forms closure conditions, which adapts to the complex measuring environment on the spot, breaks through the limitation of multiple factors to buried piles at selected points, and improves the efficiency of surveying work while saving the cost.
