Abstract

Flood protection structures (flood walls, pump plants, railroad or vehicular access opening and gatewell structures) have foundations subjected to hydrostatic pressures during flood conditions. The foundation sands below these structures are likely to produce hydrostatic pressure elevation heads which measure higher than the top of ground at the structures. Often the foundations for these structures are deep enough to penetrate the sands into the artesian pressures. Deep foundation design for the flood protection structures utilizes software programs based on load testing in many different types of soils. The load tests used to model soil-structure responses to loading are conducted on moist soils and sometimes saturated soils. Standard load testing does not model the hydrostatic load case. The high river stage will significantly change the foundation resistance for cohesionless materials. A procedure for adjusting the foundation sands subjected to excessive pore pressures is suggested.

Deep Foundation Design Near Flood Protection Projects

New York, New York

Flood protection structures (flood walls, pump plants, railroad or vehicular access opening and gatewell structures) have foundations subjected to hydrostatic pressures during flood conditions. The foundation sands below these structures are likely to produce hydrostatic pressure elevation heads which measure higher than the top of ground at the structures. Often the foundations for these structures are deep enough to penetrate the sands into the artesian pressures. Deep foundation design for the flood protection structures utilizes software programs based on load testing in many different types of soils. The load tests used to model soil-structure responses to loading are conducted on moist soils and sometimes saturated soils. Standard load testing does not model the hydrostatic load case. The high river stage will significantly change the foundation resistance for cohesionless materials. A procedure for adjusting the foundation sands subjected to excessive pore pressures is suggested.
