<p>The piezoball, or ball penetrometer with pore pressure measurement, was developed for assessing the geotechnical properties of soft soils, particularly soft seabed sediments where the traditional cone penetrometer can have limitations. The measurement of ...

<p>Many years ago it was suggested by Professor Robert E. Gibson to a group of colleagues to write a book on the theory of consolidation, as the theory of poroelasticity was then called, on the lines of the classical treatise by Carslaw and Jaeger on the Conduction ...

<p>Commercial cone penetration testing (CPT) equipment was adapted to allow penetrative testing in hard polar firn to depths of 10 m. The apparatus is hydraulically driven, rate-controllable and able to penetrate firn with a resistance of 10 MPa. It can be ...

<p>Soil behavior is complex and thus requires quantification by a reasonably good number of different engineering parameters. Consequently, the seismic piezocone test (SCPTu) is particularly well-suited to being an efficient and economical tool for routine ...

To understand the strain-dependent shear modulus and damping ratio of reconstituted pumice sand samples, a series of dynamic deformation tests was performed using hollow cylindrical torsional shear test apparatus. The effects of confining pressure level and ...

<p>This book is the text for the introductory course of Soil Mechanics in the Department of Civil Engineering of the Delft University of Technology, as I have given from 1980 until my retirement in 2002. It contains an introduction into the major principles ...

<p>In this paper, cyclic triaxial loading tests were conducted on specimens of soft clay with varying cyclic stresses and frequencies to investigate the performance of soft soil subgrade subjected to cyclic loading. The laboratory results indicate that given ...

Permeability function of an unsaturated soil, k(\), where \ is suction, is a vital hydrogeological property that governs seepage in various geotechnical problems. Owing to considerably long test duration, direct measurement of k(\) is often avoided if at all ...

The application of suction on a saturated soil specimen consolidated in an oedometer may cause the lateral shrinkage. This study tries to simulate such situation using triaxial testing apparatus and to quantify the lateral deformation due to drying and shearing. ...

<p>In the last two decades, Brillouin distributed fiber-optic sensing has became a widely accepted, mature technology. On the other hand, geotechnical monitoring applications of this technology are still rare, as the fragile fiberoptic and the harsh soil environment ...
