X線回折による圧密時の粘土構造に関する研究

Abstract

In order to investigate the effects of consolidation pressure and loading period on the soil fabric, the X-ray diffractometer equipped with a pole figure device is used. To express particle orientationquantitatively, P.R. which is the ratio of peak amplitudes of (002) to (020), and OR. Which is theratio of P.R's of H-section to V-section are employed: and then the meanig of these values isdiscussed with a simple clay model.Main results obtained are as follows: clay particles tend to be reoriented into the plane per-pendicular to the consolidation pressure with increasing consolidation pressure; remarkable re-orientation also occurs doting secondary consolidation having large consolidation pressures.
