A series of uncon solidated undrained triaxial tests were performed on specimens compacted at ·water contents ranging from 4 per cent dry of optimum to 5 per cent wet of optimum. The specimens were subjected to confining pressure ranging from 10 psi to 1000 psi, and times to failure ranged from 15 min. to 10 msec. It was found that the compressive strength of all speci mens increased as the time to failure decreased. The specimens compacted near and at optimum moisture content exhibited a higher strength increase than the specimens compacted at other water ~ontents. The strength ratio decreased slightly as the confining pressure increased. The increase in strength ratio was greater for specimens with random particle oriEn tation than for specimens with a parallel orientation.

An investigation of the dynamic shearing properties of the compacted Bangkok Clay was conducted. A series of uncon solidated undrained triaxial tests were performed on specimens compacted at ·water contents ranging from 4 per cent dry of optimum to 5 per cent wet of optimum. The specimens were subjected to confining pressure ranging from 10 psi to 1000 psi, and times to failure ranged from 15 min. to 10 msec. It was found that the compressive strength of all speci mens increased as the time to failure decreased. The specimens compacted near and at optimum moisture content exhibited a higher strength increase than the specimens compacted at other water ~ontents. The strength ratio decreased slightly as the confining pressure increased. The increase in strength ratio was greater for specimens with random particle oriEn tation than for specimens with a parallel orientation.
