Abstract: A force‐equilibrium model was used to derive a theoretical solution for the lateral capacity of rigid piers embedded in cohesionless and c‐ϕ soil profiles having sloping ground surfaces. A parametric study indicated that ...

Abstract: Site investigations conducted at the North Carolina State University Research Farm and adjacent construction sites provided the database to study the soil profile and deformation characteristics of Piedmont residual soil. ...

Abstract: Piedmont residual soils were formed by in-situ weathering of igneous and metamorphic rocks. In this research project, their dynamic properties (shear modulus and damping) were investigated by performing a combination of ...

Abstract: An approach for comparatively evaluating the performance cost of undercut subgrade stabilization measures is presented. The performance-cost analysis coupled results from laboratory cyclic load testing with material prices ...

Abstract: This paper proposes approaches to estimate effective friction angle from cone tip resistance with incorporation of matric suction. Cone penetration tests (CPTs) are performed in unsaturated residual soil layers, where ...
