Abstract

A series of cyclic triaxial tests illustrated the definite increase of the cyclic strength of silty sands with prestress. This effect is found to be similar to that measured by other researchers. Relationships giving the proportional increase of the cyclic strength in the free field with the overconsolidation ratio are proposed. Conclusions are drawn regarding the potential of using preloading to reduce the liquefaction danger in the free field. 1. Introduction Sometimes, an engineer has to construct on liquefaction-susceptible soils. According to Seed [13] one of the most prudent methods of minimizing the hazards associated with liquefaction-induced deformations is to devise remedial measures in such a way that high pore pressures cannot build
