Undrained Plane-strain Expansion of a Cylindrical Cavity in Clay: a Simple Interpretation of the Pressuremeter Test
نویسندگان
چکیده
A study is made of the problem of interpreting the results of Menard pressuremeter tests on soil in situ. In the test a cylindrical cavity is expanded by internal pressure, and the relation between applied pressure and cavity vulume change is measured. It is shown that the results of a single test are enough to determine a complete stress-strain relation in plane strain, and a simple graphical procedure for doing this is derived. The only restrictive assumption r.ecessary is that the deformation is under undrained conditions; there is no restriction to infinitesimal strain or to elastic perfectly-plastic soils.

Plane Strain Deformation of a Poroelastic Half-Space Lying Over Another Poroelastic Half-Space
The plane strain deformation of an isotropic, homogeneous, poroelastic medium caused by an inclined line-load is studied using the Biot linearized theory for fluid saturated porous materials. The analytical expressions for the displacements and stresses in the medium are obtained by applying suitable boundary conditions. The solutions are obtained analytically for the limiting case of undrained...
متن کاملPredicting ε50 for Lateral Behavior of Piles in Marine Clay Using an Evolutionary Based Approach
Analyzing piles subjected to lateral loads significantly depends on soil resistance at any point along the pile as a function of pile deflection, known as p-y curve. On the other hand, the deformation characteristics of soil defined as “the soil strain at 50% of maximum deviatoric stress (ε50)” has considerable effect on the generated p-y curve. In this research, several models are proposed to ...
متن کاملEffects of state parameter, fines content, and overburden stress on CPT resistance in silty sands
Cone penetration resistance in sands with fines contents up to 35% is explored through drained cylindrical cavity expansion simulations with a modified MIT-S1 constitutive model. The constitutive model is calibrated to sands with 0%, 10%, 20%, and 35% low-plasticity fines with data from constant volume direct simple shear, drained and undrained triaxial compression, shear wave velocity, and 1D-...
متن کاملViscous Rate Effects in Shear Strength of Clay
Viscous rate effects are commonly observed in clay soils in applications that involve high strain rates such as free falling penetrometer tests. Viscous rate effects are not well studied thus affecting reliable interpretation of these applications. This paper presents an investigation of viscous rate effects in clay using laboratory rate studies covering a wide range of strain rates (6 orders o...
متن کاملStress-Strain Behaviour of Completely Decomposed Granite in Both Triaxial and Plane Strain Conditions
Most of the field problems in geotechnical engineering are in three dimensional state or close to a plane strain condition. Strength and deformation properties of soils in plane strain condition are considerably different from those in an axisymmetric condition. Many researchers have investigated the behaviour of soils under a plane strain condition. However, most of the previous studies have c...
