Abstract:

Saturated undrained triaxial tests and air dry torsional shear tests were carried out on several sands. Two rates of strain were used, approxi mately 1000sec. and 3sec. These tests clear ly showed that dilation of sand increases with an increase of strain-rate. These tests also showed that the greatest effect of strain-rate on strength in sand occurs when the restraint of dilation is stiffest. In undrained saturated triaxial sts the strength increase due to in crease of strain-rate can be as high as 30 per cent. No pronounced effect of strain-rate on fraction angle was observed. Author
