The Teton Dam: rhyolite foundation + loess core = disaster

Ageing Effects on the Dam-Reservoir-Foundation Interaction Response of the Dez Concrete Arch Dam

In the present study, as a promotion to the previous attempt of the authors and his co-workers, Labibzadeh et. al. [1] the degradation of mass concrete of the Dez dam was evaluated in more detail using a more sophisticated numerical degradation model. In that preceding work, it was demonstrated that the concrete of the Dez dam has been deteriorated and its mechanical properties have been change...

Erosion in the Foundation of Abshineh Dam (Iran)

Seismic Behavior of Zoned Core Embankment Dam

The aim of this investigation is to study the dynamic behavior of a zoned core earth-fill dam. Due to lack of suitable clay materials, the Mamloo dam is designed as zoned core that is composed of three vertical zones including central lean clay (CL) core and two sides clayey gravel (GC) layers. Seismic behavior of dam was analyzed in two cases including homogenous clayey core and zoned core by ...

Evaluation of pore water pressure foundation and core of Sivand dam after the first dewatering period in comparison with the actual instrument results

Increasing the pore water pressure in the body of dams will reduce the effective stress and thus reduce the shear strength of the body materials of the dam, which can lead to dangerous results and cause instability of earth dams. According to nonlinear behavior of earth dam, behavioral models of Mohr–Coulomb and hardening soil model are used to model the dam and body materials. In this study, u...

Engineering Geology Considerations for Specifying Dam Foundation Objectives

In dam construction, the actual depth to adequate foundation materials at a site is known with certainty only at the points of exploration. The foundation objective serves as a descriptive tool to convey design intent information to construction engineering staff and the contractor. The selection of the most effective approach, or approaches, usually depends on site geology and the amount of av...
