AbstractAn intensive site investigation consisting of electric cone penetration tests, vane tests, Delft sampling and thin wall sampling holes has been carried out in soft alluvial soils in the Humberside area. This programme facilitated a correlation to be made between static cone end resistance with the undrained shear strengths obtained from the vane testing and laboratory test results. A discussion is presented on the various cone correlation factors (Nk) obtained and these results are compared to the cone factors established by others in similar soil conditions elsewhere.

AbstractThe paper presents the successive stages of the methodology which has been adopted for the interpretation of findings of an extensive geotechnical site investigation. This investigation was carried out in the urban area of the town of Kalamata, S.W Greece subsequent to the catastrophic earthquakes which occured in the area during September 1986. The scope of the wqrk was to determine the engineering geological characteristics of Quaternary deposits which mainly constitute the foundation materials beneath Kalamata, so that the various geotechnical groups could be presented in terms of consistent contour maps and cross-sections. To this end 25 boreholes were drilled to enable geotechnical profiling at several sites in the area of interest. Apart from borings, some 90 cone penetration tests (C.P.T.) were performed by using a mobile truck-mounted electronic cone penetrometer system with a capability of 200 KN. The cross-hole seismic technique was also used in certain boreholes to estimate Shear wave velocities (Vs), in the ground. Finally, a detailed laboratory Programme was carried out to determine the geotechnical parameters necessary for the grouping of soils in relation to their engineering behaviour.

Properties Of Soil

A method of utilizing cone penetration tests (CPTs) is presented which gives continuous profiles of both the in situ thermal conductivity and volumetric heat capacity, along with the in situ temperature, for the upper tens of meters of the ground. Correlations from standard CPT results (cone resistance, sleeve friction and pore pressure) are utilized for both thermal conductivity and volumetric heat capacity for saturated soil. These, in conjunction with point-wise thermal conductivity and in situ temperature results using a Thermal CPT (T-CPT), allow accurate continuous profiles to be derived. The CPT-based method is shown via a field investigation supported by laboratory tests to give accurate and robust results.
