Site investigation
<p>The log of a SPT in very soft clay may simply indicate a zero blow-count, or present information on the penetration – under self-weight – of the composition (sampler, rods and hammer) as recommended by some standards. The second type of information is often disregarded by design engineers due to the lack of a standard procedure for m...

A proper geotechnical site characterization has to identify the geometry of relatively homogeneous zones and define indices, strength and stiffness properties of the soils within these zones. The most widely used in situ test to define the stratigraphical profile and to estimate geotechnical parameters is the Standard Penetration Test (SPT). Although it is widel...

<p>The purpose of this paper is to present geotechnical parameters of the variegated soils from the São Paulo Formation, aiming in particular to establish correlations between stress history parameters, earth pressure coefficients at rest, deformability modules and resistance obtained through piezocone and dilatometer tests. The perfo...

<p>This paper presents a system for performing down-hole seismic test together with the piezocone test in order to<br /> determine the shear wave velocity (Vs) and for calculating the maximum shear modulus (Go); a basic parameter for<br /> analyzing the dynamic soil behavior and a reference value of the soil stiffness. The system components are...
