Abstract:

The Miocene-age Calvert formation underlying Richmond, Virginia, is highly preconsolidated and very sensitive and requires careful evaluation for foundation design. This soil is of marine origin, and preconsolidation results from desiccation associated with several identifiable drying surfaces and overburden erosion. Major structures are typically supported within this formation by spread footings and belled caissons. The high undrained shear strength and preconsolidation pressure of the formation allow the design of high-capacity foundations. The standard penetration test N-values for the soil are typically low and not indicative of its quality. Conventional triaxial compression and consolidation tests are often utilized to obtain parameters for design of foundations. More recently pressuremeter test results have been used for foundation design. The purpose of this paper is to present a summary of available laboratory and pressuremeter test data and to characterize the engineering properties of this soil.
