摘要

The pressuremeter is one of the leading tools that allow direct measurement of the soil structure interaction. Its almost full scale loading of soils during testing, its applicability to most soil types, and recently, to soft rocks has allowed major progress in the understanding, design and control of soil improvement, where treated soils will have to meet preset criteria. Structures can be designed based on Menard's rules this with a tested volume allowing the 98 % confidence in predicting the soil structure behavior, which is by far more than current practice. Indeed the approach of Louis Menard directly uses the limit pressure, PLM, as the parameter governing bearing capacity, without relying on failure criteria and hypotheses, and the pressuremeter modulus, EM, is directly related to deviatoric deformation and adopted for volumetric deformations as well. The selected case histories illustrate the essential input of the Menard Pressuremeter in various applications.
