A SIMPLIFIED CORRECTION FOR MEMBRANE COMPLIANCE IN LIQUEFACTION TESTS

A concept to account for the effect of membrane penetration on the generation of pore pressure in soil liquefaction tests was demonstrated based on experimental studies. The major effect of membrane penetration was to increase the number of cycles to cause liquefaction. The cycle ratio was defined as a ratio between numbers of cycles causing soil liquefaction with and without compliance at the same stress ratio. The cycle ratio was found to be a unique function of membrane compliance ratio, and independent of applied shear stress. A careful review of the previous study (martin et al, 1978) yielded the same result, indicating the validity of the concept. Based on the findings, a simplified method was presented for correcting liquefaction test results for the membrane penetration effects. Several previous studies concerning the effects of specimen diameter were used to validate the proposed method, since the resulting difference in the liquefaction strength mainly reflects the membrane penetration effects. The liquefaction strength curves for different diameter specimens after membrane correction were almost coincident, showing a considerable potential of the proposed method.
