Abstract

According to the current practice, the unit shaft resistance of piles based on ground parameters is calculated usually with the $$a$$-method or the $$\beta $$-method. And while the physics behind these methods is simple and adequate for calculating the shaft resistance of piles in clays and sands for total and effective stress analysis respectively, the main difficulty in applying the effective stress approach in clays is to estimate the radial effective stress acting on the pile. In the present paper this is addressed by a proposed earth pressure at-rest coefficient, applicable to cohesive-frictional soils. The proposed coefficient is the product of a fully analytical, continuum mechanics approach, which, when applied to cohesionless soils, is simplified to the well-known $${K}_{O}=1-\mathrm{sin}\varphi^ {\prime}$$, expression. Comparison examples show excellent agreement of the analytically derived shaft resistance capacities with the respective numerical ones.
