Monitoring of Tabarak-Abad Dam during Construction Using Back Analysis (Technical Note)

Tabarak-Abad dam is a clay core, earth-rock fill dam with the height of 74 m above its rocky foundation. The dam with the crest length of 193.5 m is located on the Tabarak-Abad River at north east of IRAN. Construction of the dam began on January 2003 and completed on October 2004. The dam is extensively instrumented to provide data required for monitoring. The paper will describe the instrumentation system installed in the dam body with back analyses and monitoring the water pressure, earth pressure and deformation.
