THE MENARD PRESSUREMETER TEST AND THE BEHAVIOUR OF LATERALLY LOADED PILES IN SANDS . PRESSUREMETERS. PROCEEDINGS OF THE THIRD INTERNATIONAL SYMPOSIUM, ORGANISED BY THE BRITISH GEOTECHNICAL SOCIETY, OXFORD UNIVERSITY, APRIL 2-6, 1990

Two instrumented pipes were installed at a sand site at Le Rheu, France. One pipe was 0.5 m in diameter, and the other was 0.9 m. The piles were steel pipes, installed in 5 m deep boreholes which were previously filled with Bentonite-cement grout having a compression modulus at 28 days of 3500 MPa. These piles were submitted to a static lateral loading programme. The lateral load was applied separately to each pile using an hydraulic jack located one metre above the natural ground level and equipped with a high precision electric load cell. The reaction was provided by a concrete block. The horizontal displacement of the piles was measured using an invar wire with a precision of 1/10 mm and the head rotation using BRE electro levels. The instrumentation along the pile consisted of (a) strain gauges every 0.25 m depth; and (b) access pipes submerged in the grout, allowing the installation of the BRE electro levels every 0.5 m for slope measurements. The results of these tests are compared to the predictions based on the Menard pressuremeter method and on the Brinch Hansen method. The influence of pile diameter is specifically studied. The Menard P-Y pressuremeter method gave results comparable to those obtained in the full scale tests for relatively high levels of loading. For actual design of laterally loaded piles, it is recommended that the reaction pressure be limited to the creep pressure. The allowable load and corresponding maximum bending moment determined by using the Menard limit pressure/3 in a classical statistical approach produces results similar to those obtained by applying the Brinch Hansen method.
