摘要
在饱和粘土上建造公路,工程界最关心的是地基稳定和变形问题。分析土壤微观结构对防范地基的坍塌、下陷和变形有非常重要的意义。通过对取到的土样在真空下进行干燥,用Hitachis＿3500N电子扫描电镜进行拍摄得到了一些土壤灰度图像。通常采用的方法都是对电子显微镜拍摄的照片进行二维处理,既丢失了不少特征,又不直观。本文主要介绍如何利用OpenGL来实现土壤微观结构图像的三维重建,从而获得对土壤微观结构特征进行分析的一种新的分析方法。
The question that engineers most care for is groundwork's stabilization on building a road on saturated clay. The analysis of soil microstructure has very important signification to keep away groundwork's collapse, sink and distortion. By evaporating soil stylebook in vacuum and shooting the stylebook by electron microscope then, finally, some soil microphotographs are got. Usually, most ways that process the microphotograph are localized in twodimensional space, these ways can't provide conspicuous characters. This article introduces how to use OpenGL to realize soil microphotographs' threedimensional reconstruction, so as to get a new way to analyzing soil microstructure.
