Based on a variety of case histories of site investigations, including extensive bore hole data, laboratory testing and geophysical prospecting at more than 550 construction sites, an empirical formulation is proposed for the rapid determination of allowable bearing pressure of shallow foundations in soils and rocks. The proposed expression corroborates consistently with the results of the classical theory and is proven to be rapid, and reliable. Plate load tests have been also carried out at three different sites, in order to further confirm the validity of the proposed method. It consists of only two soil parameters, namely, the in situ measured shear wave velocity and the unit weight. The unit weight may be also determined with sufficient accuracy, by means of other empirical expressions proposed, using P or S -wave velocities. It is indicated that once the shear and P-wave velocities are measured in situ by an appropriate geophysical survey, the allowable bearing pressure as well as the coefficient of subgrade reaction and many other elasticity parameters may be determined rapidly and reliably.

“…The P and S seismic velocities of the layers were calculated using the Esos-Seisimager evaluation program. Using the experimental equations found in studies [32][33], [25] and [34], the elasticity modulus of rocks was determined using P and S seismic velocities values. The mean calculated P and S wave velocities were given in Table 1.…”

Abstract:In rock mechanics, various methods are available to detect the rock properties. The aim of this study is to determine physical and mechanical properties of the serpentinized ultrabasic rocks such as Eğirdir-Kızıldağ Harzburgitic Peridotites. The serpentinized ultrabasic rocks are commonly used for architecture and the ground under road bases in many areas and also widely used for indoor elements such as tables, pilasters and ornaments of different kinds. In this study, geophysical and geotechnical tests including P and S-wave velocities, rigidity modulus, Poisson ratio, elasticity modulus, bulk modulus, natural period, safe bearing capacity and bedding coefficient were performed on nine rock samples, collected from different areas. Geophysical and geotechnical studies were carried out both parallel and perpendicular to foliation planes of the cubic samples. Ultrasonic P-Wave Velocity (UPV), Uniaxial Compressive Strength (UCS), volumetric water contents, effective porosity, unit volume weight, density and weight of all samples were calculated. Finally, statistical relations among the measured parameters were established by using regression analysis.

“…As shear strain increases, the initial shear modulus will decrease from the maximum small-strain value. In-situ tests have commonly been assumed to be small-strain and the measurement of shear wave velocity will be directly related to the maximum shear modulus [6]. The appropriate shear strain must be known, as well as the appropriate modulus reduction with increasing shear strain.…”

The Ultimate Pile Bearing Capacity from Conventional and Spectral Analysis of Surface Wave (SASW) Measurements

et al. 2018

View full text Add to dashboard Cite

Abstract.A conventional and seismic method for determining the ultimate pile bearing capacity was proposed and compared. The Spectral Analysis of Surface Wave (SASW) method is one of the non-destructive seismic techniques that do not require drilling and sampling of soils, was used in the determination of shear wave velocity (Vs) and damping (D) profile of soil. The soil strength was found to be directly proportional to the Vs and its value has been successfully applied to obtain shallow bearing capacity empirically. A method is proposed in this study to determine the pile bearing capacity using Vs and D measurements for the design of pile and also as an alternative method to verify the bearing capacity from the other conventional methods of evaluation. The objectives of this study are to determine Vs and D profile through frequency response data from SASW measurements and to compare pile bearing capacities obtained from the method carried out and conventional methods. All SASW test arrays were conducted near the borehole and location of conventional pile load tests. In obtaining skin and end bearing pile resistance, the Hardin and Drnevich equation has been used with reference strains obtained from the method proposed by Abbiss. Back analysis results of pile bearing capacities from SASW were found to be 18981 kN and 4947 kN compared to 18014 kN and 4633 kN of IPLT with differences of 5% and 6% for Damansara and Kuala Lumpur test sites, respectively. The results of this study indicate that the seismic method proposed in this study has the potential to be used in estimating the pile bearing capacity.
