Menard Lecture The pressuremeter test: Expanding its use Conference Paper uri icon

abstract

  • The purpose of this contribution is to show how the use of the PMT can be expanded further than current practice. The topics covered in a first part include the amount of soil testing necessary to meet a reliability target, the influence of the lack of tensile resistance of soils on the PMT modulus, how to recreate the small strain early part of the curve lost by the decompression-recompression process associated with the preparation of the PMT borehole, best practice for preparing the PMT borehole, commonly expected values of PMT parameters, the use of the PMT unload-reload modulus, and correlations with other soil parameters. The second part deals with foundation engmeermg and includes the use of the entire expansion curve to predict the load settlement behavior of shallow foundations, the load displacement behavior of deep foundations under horizontal loading, foundation design of very tall structures, long term creep loading, cyclic loading, and dynamic vehicle impact. Finally an attempt is made to generate preliminary soil liquefaction curves base on the normalized PMT limit pressure.
