The Effect of Cut-off Wall on Seepage and Uplift Pressure under Earth Dam (Case Study: Shamil Dam in Iran)
Design of earth dams and their problems are important during construction and after it,because of their potential hazards and failure for downstream population. The dam foundation seepage control the the importance from the perspective of a major engineering project and explain the economic performance of each project is allocated. among activities that can be used to prevent piping phenomena a...
متن کاملTrial Chemical Grouting in Filter Materials at the Karkheh Dam Site, Iran
A sodium silicate-based chemical grout was used in the Karkheh dam site in order to examine the performance of the chemical grouting technique for stabilization of the dam's filter material. Karkheh, an embankment dam with the reservoir capacity of about 7.4 billion cubic meter at the maximum water level, is the largest dam in Iran. The grouting works performed at the dam site, were part of the...
متن کاملconstruction and validation of the translation teacher competency test and the scale of students’ perceptions of translation teachers
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
Deformation Performance of the Karkheh Earth Dam with Mixed and Pure Clay Coreunder Seismic Excitations
The number of constructed dams has been largely increased due to high demands of water supplies, and earth dams are the most common types since they are more compatible to the environment. Nevertheless, the stability of these important structures during earthquakes has to be carefully evaluated and guaranteed. In the past, earth dams usually designed with pure clay core, but in recent decades t...
متن کاملconstruction of relief wells under artesian flow conditions at dam toes: engineering experiences from karkheh earth dam, iran
we report engineering experiences from the critical task of relief well installation under high artesian flow conditions at the downstream toe of the karkheh earth dam, iran. due to the establishment of excessive uplift pressure at the downstream toe of the karkheh dam, installation of a series of new relief wells was considered to permanently relieve part of these pressures. the mentioned upli...
