Then after closure, taking steel perimeter beam and perimeter beam rail as slip base, in order of symmetrical balance, hoisting each steel "leaf" respectively up to the installation platforming of steel leaf, again by utilizing the steel perimeter beam, perimeter beam rail and hydraulic thrusting slip equipment, performing the installation for the eight steel leaves until they are closed together.

施工中采用了&一点吊装、平面滑移&的技术进行安装，即采取同一固定点吊装，先将分段钢环梁利用环梁轨道和液压顶推设备滑移，分段逐步滑移和顶推、逐步拼接，直至钢环梁合拢。将合拢后的钢环梁和环梁轨道作为滑移底座，按对称、平衡的顺序将每片钢叶瓣分别吊装至安装平台上，再次利用钢环梁、环梁轨道和液压顶推滑移设备，将8片钢叶瓣逐步安装到位。

The basic principle is that basic geometry shape of openings in the photo is revised; the image can't be distortion by use of projection reconstruction; the corrected image is exerted by open operation and close operation of gray-image; the shape of openings is gained lastly. The perimeter borderline of openings shape is extracted. The quantity of overbreak as well as underbreak is gained by comparing to extracted perimeter and designed perimeter. The same method is applied to other opening sections. Evaluation of overbreak as well as underbreak in the openings can be easily solved in the way of quantitative.

其基本原理是：对野外摄取的洞室的基本剖面形状进行几何校正，然后应用图像学中的投影重建方法使图像不失真，对修正后的图像实行灰度图像的开操作和闭操作运算，得到洞室的基本形状，然后用图像学中的边界提取技术提取洞室的周边界，与洞室的设计形状对比分析，得到洞室在该断面上的超欠挖方量，然后对其它断面采用同样的技术就可评价某一段或整个洞室的超欠挖数量，从定量的角度解决了工程中的超欠挖评价问题。
