Abstract

A case history of hydrostatic pressure development along the soil-structure interfaces of a water retaining structure is discussed in this paper to illustrate the use of instrumentation to verify expected performance during construction. For the project described, the development of hydrostatic pressure along the soil-structure interface during and after head pond watering was monitored using pneumatic piezometers. Monitoring of the piezometers detected a high hydrostatic pressure caused by a leaky contraction joint seal. Subsequent repair of the seal reduced water levels along the interface to expected levels, resulting in successful operation of the facility.

Hydrostatic Pressure at a Soil-Structure Interface

A case history of hydrostatic pressure development along the soil-structure interfaces of a water retaining structure is discussed in this paper to illustrate the use of instrumentation to verify expected performance during construction. For the project described, the development of hydrostatic pressure along the soil-structure interface during and after head pond watering was monitored using pneumatic piezometers. Monitoring of the piezometers detected a high hydrostatic pressure caused by a leaky contraction joint seal. Subsequent repair of the seal reduced water levels along the interface to expected levels, resulting in successful operation of the facility.
