摘要: 采用近景摄影的方法,以获取隧道开挖的实态轮廓线,从而获得任意断面的超挖、欠挖数据.另外,通过前后两次的测摄可获取围岩的变形数据,利用以上数据可对隧道围岩结构进行受力分析、计算,也可确定最佳二次衬砌时间.

关键词: 近景摄影, 实态轮廓, 围岩变形

Abstract: In this paper, the real-state outline of tunnel excavation is obtained by a close-range photopraphic method.Thereby the over-under-excavated data of any section of the tunnel are found out.In addition, the deformation data of the surrounding rock can be obtain from the surveying results in front and behind.These data can be applied to analyze the stresses of the tunnel structures and determine the best second lining time.

Key words: close-range, real-state outline, deformation of surrounding rock
