Limited flow characteristics of sand with fines under cyclic loading

Abstract

Experimental studies on a sand with a well-graded low plasticity fines were conducted to study a number of issues related to limited flow. Cyclic behaviour in relation to instability and limited flow are compared with corresponding monotonic behaviour. A single set of rules for a range of fines contents was proposed to correlate cyclic and monotonic behaviour.

Keywords:

• instability
• cyclic loading
• fines
• limited flow
• strain softening
