Image processing applied in the evaluation of overbreak and underbreak in the tunnels is a new trial in the geological and geotechnical engineering.

圖像處理技術(shù)在隧洞超欠挖評價中的應(yīng)用是該技術(shù)在地質(zhì)及巖土工程領(lǐng)域的新嘗試又黄又爽又色无遮挡18禁网站。

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 underbreak in the tunnel is solved quantitatively.

通過對野外攝取的隧洞圖像進行一系列的處理得到隧洞的基本形狀91狠狠综合久久久久精品网站，然后與隧洞的設(shè)計形狀對比分析国产精品婷婷久久久久久，即可得到隧洞在該斷面上的超欠挖方量日韩视频自拍第二页在线播放网站，然后對其他斷面采用同樣的技術(shù)就可評價某一段或整個隧洞的超欠挖數(shù)量A片欧美AAAAAA，這樣就從定量的角度解決了以往工程中難以解決的超欠挖評價問題，為工程超欠挖的判斷與決策提供合理依據(jù)黄片一级无码视频在线。
