Site characterization of reclaimed lands based on seismic cone penetration test by Wang, Hao, Wu, Shifan, Qi, Xiaohui, Chu, Jian

“…The derived correlations for the fill materials are found to be significantly different from those proposed for intact soils in literature, mainly due to the difference in geological history and material composition. The application of the new correlations is illustrated through three independent case studies. …”
