摘要
采用基于激光三角法的测试方法对混凝土断面表面轮廓进行了三维重构 .初步的断面分析结果表明 ,相对于传统断面分析方法 ,本试验方法实现了断面的无损、快速和准确的测量分析 .在测量到的断面基础上 。
A new experimental technique based on laser triangulation was used to reconstruct the 3 D fracture surface of concrete. Preliminary analysis results showed that,compared with the traditional analysis methods,this new technique could perform a nondestructive,speedy and accurate analysis of fracture surfaces. Based on the reconstruction of 3 D fracture surface, the correlation between fracture energy and fractal dimension was shown.
