| 摘 要： | 图像处理技术在隧洞超欠挖评价中的应用是该技术在地质及岩土工程领域的新尝试。通过对野外摄取的隧洞图像进行一系列的处理得到隧洞的基本形状,然后与隧洞的设计形状对比分析,即可得到隧洞在该断面上的超欠挖方量,然后对其他断面采用同样的技术就可评价某一段或整个隧洞的超欠挖数量,这样就从定量的角度解决了以往工程中难以解决的超欠挖评价问题,为工程超欠挖的判断与决策提供合理依据。最后通过一实例对某一隧洞的超欠挖方量进行评价。

| Abstract: | Image processing applied in the evaluation of overbreak and underbreak in the tunnels is a new trial in the geological and geotechnical engineering. The shape of tunnel is gained by use of many processing ways to the initial images in the field. The quantity of overbreak and underbreak is gained by contrasting between the extracted shape and the designed shape. The same method is applied to other tunnel sections then the overbreak and underbreak quantity of a certain section or the total tunnel is gained so the problem about the evaluation of overbreak and underbreak in the tunnel is solved quantitatively. The engineering example is used to evaluate the overbreak and underbreak of a certain tunnel. |
