GEOTECHNIQUE, V24, NI,MAR. 1974, P93-99. The effect of non-unlform stress distribution on a diaphragm type earth pressure cell using strain gauges on the active diaphragm is investigated, with the intention of finding some means to minimize the effect of non-unlfca~m pressure distribution in the initial design stage of the earth-pressure cell °
The Wsxman-Smlts physical model for describing conductivity in ahaly-sard has been extended to allow for oil-bearing sands, and the required assumptions have been confirmed by laboratory measurements; A conclusion from the tests is that the effective concentration of clay-exchange cations increases in proportion to the decrease in water saturation. The temperature coefficients of electrical comductivity for a group of shaly-sanls were measured and these data were treated by the same model.

GEOTECHNI QUE, V24, N1, MAR. 1974, P45-62. An investigation into the actual flow patterns in granular fill during discharge from tall silos is described. Model silos of different sizes were used and three separate gradings of fine gravel fill were tested for various port openings centrally located. Two methods of investigating the nature of flow were employed, concentric cylinders of coloured gravel fill and rsdioactive labelling. The work indicated four separate zones of flow occurlng within the fill.
