Abstract

Dredged fills have been widely used to secure a land for the engineering activities. Before the useful application of the area, the soils should be consolidated to acquire the aquate shear strength. Several research projects have attempted to develop a method fur accelerating the consolidation of soft clay. Our study examined the effect of ultrasonic energy on the consolidation of soft clay, Tests were conducted using specially designed and fabricated equipment that was capable of directly applying ultrasonic energy to soil samples during consolidation tests. The specimens were prepared from slurry using a centrifuge facility, and tests were conducted at various levels of ultrasonic power and treatment time. The study showed that ultrasonic energy had a considerable effect on consolidation time, suggesting that ultrasound can be used to reduce the consolidation time of soft clay.
