Variations in Pressuremeter Testing Results

Radhi Alzubaidi

Abstract—Some problems of measuring untrained strength and deformation properties for glacial till are presented. These soils are stiff and have low compressibility. Because of their strong fissured character, satisfactory sampling for laboratory testing presents great practical problems. A number of new pressuremeter suitable for testing glacial till in situ with constant rate of membrane expansion are carried out. The results of insitu horizontal total at rest stress, at rest earth pressure ratio, limit pressure, Undrained shear strength and Elastic Modulus for four sites in Glasgow till deduced from pressuremeter tests using different methods are presented Long time delays between completion of boring and pressuremeter testing produce considerable effects on the undrained parameters of the clay soils. The undrained shear strength, modulus of deformation and limit pressure showed appreciable reductions while the horizontal at rest pressure increases with time. A special tool was developed for extracting samples from the sidewall of the borehole so that moisture content changes can be monitored.

Index Terms—Pressuremeter, horizontal at rest pressure, undrained shear strength, elastic modulus, moisture content.
