Abstract

The existing CPT and SPT correlations are mostly limited on silica sands. It is seldom to seen the correlation are based on calcareous sand. Since the calcareous sand are mostly characterized a higher crushability and compressibility，the existing correlation is not applicable. Therefore，it is necessary to extend the CPT-SPT correlation in calcareous sands. 334 group high quality data were collected from New Doha Port project in Qatar and applied to the existing correlations to compare their applicability. The comparative results indicated that the correlation with single factor, either mean diameter D₅₀ or fine content FC(%)(＜0.063 mm)is not applicable to calcareous sand，and the coefficient factors based on CPT soil type method is relatively higher，whereas the typical correlation based on soil behave type index I_c shows a good consistency in calcareous sand. Meanwhile, one correlation method based on corrective factor is proposed and the analysis result shows a better correlation coefficient. Hence one more reliable correlation based on calcareous sand can be provided in future research.
