Part of: Settlement of Shallow Foundations on Cohesionless Soils: Design and Performance

Abstract:

The settlement and bearing capacity rules for the design of shallow foundations on sands using the results of pressuremeter tests are reviewed. The results of four footing tests to failure on a compact sand, three footing tests to failure on a dense sand, and three footing tests to failure on a silt are used together with pressuremeter test results to evaluate the existing rules. New simplified design rules are proposed. L. Menard's equation for settlement is proven reasonably accurate. An elasticity approach to settlement calculation using the pressuremeter modulus is proposed.
