| Research Abstract |
In this report, some details regarding in-situ/lab measurements of wave velocity, together with their comparisons are outlined, bearing the above-mentioned 'trinitarianism' in mind. Application of in-situ seismic tests in understanding engineering properties of various geomaterials is discussed. Lastly, two case histories, each demonstrating the importance of in-situ seismic survey in geotechnical site investigation scheme are described in detail.
Quasi-elastic stiffness (QES) in shear behaviour of geomaterials is discussed. Recent developments in measurement of QES of natural ground by a means of in-situ seismic survey, together with comparable measurement of elastic wave velocities in the laboratory are outlined. Application of combined in-situ/lab measurements is discussed with reference to the interlink between QES and strengths, the quality of laboratory sample and the in-situ 'structure' of natural sedimentary clay. Two case records, each demonstrating the importance of in-situ seismic survey are described : these are i)prediction of soft clay ground deformation associated with deep excavation in Bangkok Metro project, and ii)geotechnical site investigation performed at leaning tower of Pisa in September 2003.
