Fig. 5. Variations of Kc (MPa) with D50 (mm) for different sandy soils. According to Chin et al. (1988), the percentage of fines (FC) is inversely proportional to the Kc values. The percentage by weight of fines in the soils of Vitoria ranges from 0.3% to 3%, with a medium FC ...
Several researchers have evaluated the low strain dynamic properties (VsandGmax) for different soils by empirically correlating them with indirect methods such as SPT N-values. Schmertmann [5] observed thatGmaxdepends on the dynamic stress-strain properties of the soil and the level of strain in...
A standard penetration test (SPT) is one of the in-situ tests conducted for onshore and near shore soil investigation projects. SPT test data are extensively used for estimation of soil design parameters needed for geotechnical analysis. However, quality
All Soils In this study, 74 data pairs (VsandN) were employed in the assessments. The correlations were developed using a simple regression analysis. In the analyses, new relationships were proposed betweenVs(m/s) andNvalues. However, before this, effect of correction onNvalues has been exami...
The influence of the effective overburden pressure on the standard penetration test (SPT) values in calcareous desert sands is examined by field tests. A simple field testing procedure is proposed and employed in Kuwait at five sites having different relative densities for the surface soils. The co...
► Review of existing SPT N versus shear modulus correlations used for site response and microzonation study. ► Comparison of shear modulus correlations for different soil type with its strength and weakness. ► Highlight role of hammer energy in measured SPT N values. ► Propose a new...
stratum description, results of soil physical property tests (such as grain size distribution, uniformity coefficient, coefficient of gradation, void ratio, water content, specific gravity, unit weight, liquid limit, and PI), soil classification, P- and S-wave velocities, and SPT–N values. EGDT...
(V) profiles were coherent with the borelog showing the gradual increase in the velocity values from gravelly silty sand at the top to weathered limestone at the bottom of boreholes. However,VSprofiles obtained from CHT showed higher values than those obtained from MASW. These data was ...
Expressions for modified SPT N 1 values for different soils, i.e., for different initial SPT N 1 values, were determined as functions of replacement ratio from the available field data. Improvements in the ground are presented in the form of modified or improved SPT N 1 values versus ...
