【摘要】：針對隧道洞內(nèi)控制測量目前普遍采用的支導(dǎo)線和雙導(dǎo)線網(wǎng)兩類方法的不足,研究并提出了一種長大隧道洞內(nèi)虛擬雙導(dǎo)線測量技術(shù)方案,采用一條真實(shí)存在的支導(dǎo)線和一條內(nèi)業(yè)虛構(gòu)的虛擬支導(dǎo)線組合成虛擬雙導(dǎo)線測量方案,使其既具有常規(guī)的支導(dǎo)線簡單快捷優(yōu)點(diǎn),又具有常規(guī)雙導(dǎo)線多余觀測形成閉合條件的特點(diǎn),適應(yīng)現(xiàn)場復(fù)雜的測量環(huán)境,突破多因素對選點(diǎn)埋樁、測量的限制,在節(jié)省費(fèi)用的同時提高了測量作業(yè)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.
