Study on consolidation and liquefaction characteristics of sand with cementation effect

Abstract

Liquefaction of Pleistocene sand has been out of the scope of conventional liquefaction assessment, but it has been recently discussed more in practical field. This paper focuses on cementation, which is the main characteristic of Pleistocene sand, and consolidation and undrained cyclic loading were applied on artificially cemented specimens with measurement of shear wave velocity. As a result, the change in shear wave velocity during consolidation was less dependent on void ratio at non-cemented specimen than at cemented specimen. Increasing cementation content delayed the development of strain during undrained cyclic loading and resulted in transition to tougher failure mode.
