... with increasing velocity properties with depth. The new method has been applied at the soft clay test site at Bothkennar, and the results of this survey are compared with S h,h and S v,h wave velocity profiles obtained using conventional crosshole survey techniques at the site. The seismic data are further...

...A. B. Hawkins; W. J. Larnach; I. M. Lloyd; D. F. T. Nash Abstract The Science and Engineering Research Council recognized the need for a soft clay test bed site in Britain. The agreed specification was for a site of at least five hectares of normally consolidated material with a plasticity index...

... failure levels, which occurred at 1 – 2% axial strain in triaxial tests on the Bothkennar clay. Clayton et al. (1992) noted that if the effects of tube sampling are not accounted for, either by normalization or by reconsolidation procedures, the measured undrained strength of sediment will be more...

... Abstract The Engineering & Physical Sciences Research Council research site at Bothkennar is located on former intertidal mudflats adjacent to the Forth estuary, which were reclaimed for agricultural use around the year 1784. A desiccated surface crust has developed in the 200 years...

... for the Windermere Interstadial (WI) in the western Forth valley. Detailed faunal (ostracod and macrofauna) and sedimentological (particle size and micromorphology) examination of the 2.28 m sequence at Moss-side of Boquhapple suggests the existence of a shallow fjord-style margin environment at the site...

..., which is still used in ‘Section 5 Geophysical field investigations’ of BS 5930:2015 ( BSI 2015 ). It is not possible to mention all the QJEGH geophysical contributions over this last 50 years, but using this well-tested framework, the remainder of this review highlights some exemplars of innovations...

... laboratory testing. This, combined with the time frames required for sample preparation and testing, suggests that alternative methods are required to determine the in situ stiffness of the till. On site, pressuremeters can be used to measure in situ strength and stiffness parameters of soils...

... and undrained strength results are from Hight et al. (1992). These latter data all relate to Laval samples, so sample disturbance in both types of tests is likely 15 to be similar; for consistency with data from other sites, yield stresses are based on incremental load tests. Strength data are from...

... reference sites for the ECF ( Sutherland 1993 ). The significance of the claypits is further emphasized by their position relative to the retreating Scottish ice-sheet before 13 ka BP (and thus the dating of recession), and to the timing of the influx of fully marine water into the western part of the North...
