X線CTを用いた三軸圧縮下における砂の3次元変位特性の解明

抄録

The purpose of this paper is to evaluate displacement property of sand in three dimensions using X-ray CT. Here in this paper, the displacements in the soil are visualized under triaxial compression. So called “Yamazuna sand” which has the wide range of the size of soil particles is used in this test and the displacement property is evaluated by tracing a large number of the represented soil particles in the resulted X-ray CT images. First of all, the displacements in the soil under one dimensional compression are visualized in order to develop the proper image processing analysis and this method is also used in the case of triaxial compression test. Finally, the displacements in the soil specimen are visualized and also quantified as well in three dimensions.
