| 摘 要： | 目前国内超长隧道(洞)工程越来越多,但迄今为止,国内外20～50 km的超长隧道(洞)的横向贯通误差允许值尚无规范可循,在对洞外GPS平面控制网、洞内狭长导线网的布设以及测量误差对横向贯通误差的影响进行深入研究的基础上,提出了影响值的估算方法,通过大量模拟计算,并根据山西省引黄工程超长隧洞的测量和贯通实践,给出了超长隧道(洞)工程横向贯通误差允许值表,可供制定相应的规范和类似的工程实践参考.

| Abstract: | With the rapid development of economic construction in China, super long tunnels are becoming more and more, up to now there is no specification about the allowable value of lateral breakthrough error for super long tunnel from 20 to 50 kilometers. Based on research on design of GPS network outside and traverse network inside tunnel we proposed a method to calculate the influence value caused by control surveying errors. Through a lot of simulative calculations and combined with piercing practice of super tunnels in Wanjiazhai Project Shanxi province we give out an allowable value table of lateral breakthrough error for super long tunnels from 20 to 50 km finally, which is very important and valuable both for specification modifying and application. At the same time the network design outside and inside tunnel is also discussed. |
