Abstract. Liquefaction is considered as a major crucial hazard among different seismic risks. Ground improvement methods commonly employed, to improve the natural site conditions under such situations, lead to better performance of various engineering structures built up on.

The strength of post-liquefaction deformation and failure patterns are closely related to the distribution of powdery layer. The work provides new research evidence on the liquefaction and failure mechanism of saturated sands with stratified structure under cyclic loading which often happen during earthquakes.

In other words, cyclic liquefaction occurs when in situ static shear stresses are small compared to intermittent shear stresses. Cyclic liquefaction requires undrained cyclic loadings so that it occurs in zero effective stress conditions. During the cyclic liquefaction, effective stress at point zero, there is no shear stress.

23 Jan 2019 In strain-based procedure, the liquefaction potential is determined by the level of excess pore during undrained cyclic loading than shear stress (Hazirbaba & Omarow, 2015, 2018). The desired layer height was achieved by using a manual tamper.

Soil Liquefaction During Earthquakes – The Cliffs Notes Version Irvine, California Ross W. Boulanger June 11, 2009 This seminar is based on: • Materials from the Monograph (MNO-12) published by EERI in 2008, and • Materials presented at the EERI Seminars by I. M. Idriss & R. W. Boulanger in Pasadena, The relationships between the initial axial pressure, the confining pressure, the PWP and the load cycle number under cyclic loading and the effective stress path are presented Fig. 13b. Fig. 13 implies that the “continued liquefaction” occurs when the confining pressure and the PWP increases to the magnitude of the initial axial pressure.
