混凝土断裂面三维重构

Three Dimensional Reconstruction of Fracture Surface in Concrete

基于激光三角测距原理，提出了一种新的分析混凝土断裂面的测量方法．与传统断裂面分析方法相比，该测量方法能够对混凝土断裂面进行快速三维重构并具有无损、快速和准确的特点，还可以根据重构的断裂面对断裂面进行多种分析．计算了混凝土断裂面的分形维数和粗糙度指数．

A new test method which can be used to reconstruct three dimensional fracture surface of concrete is proposed based on the principle of laser triangulation. Compared with traditional methods, this new method is quicker and more accurate, and does not damage the surface. It can provide vast information for various analyses of the fracture surface. In the paper, the fractal dimension and roughness index of fracture surface in concrete were calculated.
