PRESSUREMETER TESTS ON STIFF CLAY AND SOFT ROCKS: FACTORS AFFECTING MEASUREMENTS AND THEIR INTERPRETATION . FIELD TESTING IN ENGINEERING GEOLOGY. PROCEEDINGS OF THE TWENTY-FOURTH ANNUAL CONFERENCE OF THE ENGINEERING GROUP OF THE GEOLOGICAL SOCIETY, SUNDERLAND POLYTECHNIC, SEPTEMBER 4-8 1988

This paper summarizes the results from pressuremeter tests performed on a number of stiff clays and soft rocks (London clay, Gault clay, glacial clays, chalk and Keuper Marl). The tests included: the newly developed in situ loading tests on 865 mm diameter plate in 900 mm boreholes; large plate tests; triaxial tests; Menard, self boring, (SBP) or push in (PIP) pressuremeter tests; and soil profile tests. The results obtained at each site are discussed and shown to depend upon a number of factors including: the type of instrument used; the method of insertion of the instrument; the soil: its fabric and stress history; and the methods of analysis. The pressuremeter results are compared with those obtained from other test methods and the full scale performance of instrumented foundations. Advice on the selection of the most appropriate methods to be used in any one circumstance and on the interpretation of the results obtained is provided. For the covering abstract of the conference see IRRD 832042.
