    摘要: Method and apparatus for testing soil samples in which two similar samples of soil to be cyclic simple shear tested are positioned on opposite sides of a loading plate and subjected to a load normal to the plate. Simultaneously, the plate is moved transversely to apply a dynamic load to the samples. Soil response is studied by monitoring both loads and the transverse movement of the plate.

    摘要: A non-contacting gauge for measuring small variations in the surfaces of objects comprises:(a) a chamber separated into two sub-chambers by a vibrating diaphragm,(b) a nozzle for each sub-chamber,(c) a reference surface adjacent to one of the nozzles, and,(d) a frame holding the chamber and reference surface moveable relative to the surface to be gauged and adapted to bring the other nozzle into the vicinity of the surface.The gauge is a versatile instrument which, while particularly suitable for measuring changes in the dimensions of geological core samples to determine residual strains, is also suitable for a range of measurement problems.
