INSTRUMENTS DEVELOPED BY THE TRRL FOR STUDYING THE BEHAVIOUR OF EARTHWORKS

A description is given of instruments which have been developed by the earthworks and foundations division of the Transport and Road Research Laboratory for measuring settlement, porewater pressure and total pressures in soil masses. In addition a recently developed apparatus for recording automatically the data from in-situ permeability tests is described. The instruments have been employed at a number of full-scale investigations of the settlement and stability of road embankments and the performance of the gauges in these studies is briefly described. (a). The covering abstracts for the symposium are IRRD Nos. 213000 and 213001. /TRRL/
