FOUNDATION TREATMENT OF OHUCHI DAM

Ohuchi 30_5

The present study was designed to investigate the effects of fermented miso (fermented soybean paste) on the induction of colon tumors by azoxymethane (AOM) in male F344 rats. A total of 91 rats, 6 weeks of age, were divided into 5 groups and given weekly subcutaneous injections of AOM (15 mg/kg body wt) for 3 weeks. The animals were placed on diets one week before the first AOM dose: commercia...

Sensitivity analysis of dynamic response of dam-reservoir-foundation system due to foundation material

The present study investigate the effects of mechanical properties of the rock layers in the foundation of concrete gravity dam on the seismic response of gravity dam–reservoir –foundation systems. The mutual effects of different domains are considered in the present research. As a case study the biggest section of Shafarud dam in the north of Iran is modeled two dimensionally using ABAQUS soft...

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)

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...
