Abstract

本研究では,マイクロフォーカスX線CTスキャナを用いて,ゴムチップ混合固化処理土供試体の密度分布や内部構造を観察した。また,ゴムチップ混合量の異なるいくつかの供試体について一軸圧縮試験の途中段階でX線CTスキャンや透水試験を行うことにより,せん断中の供試体内部の亀裂の進展状況と透水係数の変化について検討した。この結果,ゴムチップを混合することによって固化処理土の靭性が増し,透水係数の上昇が抑えられることを示した。

In this study, density distributions and inner structures of cement treated clay with tire chips(CTCT) were evaluated by using a micro-focus X-ray CT scanner and both crack propagations and change of permeability of CTCT under shear deformation were investigated by using the CT scanner. In this report, ductility change and permeability change of CTCT under shear deformation were discussed by comparing the test results and X-ray CT results and the effect of tire chips to those points were clarified.
