Parry 1 ABSTRACT Although the shear strength expression proposed by Coulomb (1776) for masonry, brick and earth, made up of cohesion and friction components, is still in general use today, it was not until Terzaghi...

.... The soil and its reinforcing elements act in combination to increase the shear strength of the soil mass, reduce its settlement under the load, and improve its resistance to liquefaction. The reinforcing element can be either inserted in the in situ soil or placed in the soil mass as it is constructed...

The paper focuses on retaining structures, underpinning of buildings, and tunnelling. Residual shear strength of the ground is considered an essential...

... on samples cut at different angles. While existing data would seem to suggest that the variation of cohesion (undrained shear strength) with orientation due to soil anisotropy is more significant than the effects of friction angle, the effect of friction angle variation should not be ignored. Arthur...

The scrap tire reinforcing system herein described mobilizes predominantly the interface shear resistance, which is close to the backfill soil shear strength. Simultaneously, this system is more flexible than the conventional ones...

... be improved is nearly 25 times its original value of undrained shear strength. Given a safety factor of 3, the safe bearing capacity could be improved to a maximum of 8 times the Cu value. In the same manner the settlement of the ground can be reduced only to a limiting value as indicated in Figure 3. Spacing...

... level would effectively limit the deflection of a 12m deep sheetpile wall and minimise the ground movement. Ground improved by jet grout technique could achieve much higher shear strength and this would help to resist slip circle failure and ground heave. Moreover, a jet grout layer would also act...

... ABSTRACT: Shear strength of clays will generally increase with consolidation under load. Large embankments on soft clays can be constructed by adopting a staged construction approach utilising the strength increase associated with consolidation. This paper presents a case history of a staged...

In addition, the sand mixed with the HCCE material was found to be a useful fill material on soft ground based on the results of the slope stability analysis. INTRODUCTION Waste...

Calculation of the factor of safety is based on a mathematical analysis which determine the ratio between shear stress and shear strength of the slope Shear Strength is defined as : ( t ) = c + tan ( s - u) tan f Where : t = shear strength of material, kPa ; c = cohesion, kPa s = normal stress acting...
