線形判別関数を用いた新旧コンクリート打継面の付着特性評価法

摘要

In order to clarify the relationship between the roughness of the concrete construction joint and the adhesion strength, surface treatment was applied to the old concrete, test specimens on which new concrete were cast were manufactured, and adhesion shear test was carried out. Furthermore, the usefulness of the linear discriminant function was investigated to obtain the relationship between surface roughness and adhesion failure mode.%• DICMを用いて表面粗度の定量化が出来た.·表面粗度と破壊形態から線形判別関数を導出することが でき，実際に判別を行うと82.6%の精度で破壊形態を推測 することができた.
