Abstract

Dam behavior analysis is pivotal for ensuring safety, validating design predictions, and accumulating knowledge for future projects. This study focuses on the Haraz Reservoir Dam, currently under construction on the Haraz River in northern Iran. This earth-fill dam with a clay core and mixed (GC) shell stands at a crest length of 373 meters and a height of 150 meters, holding a reservoir volume of 230 million cubic meters. The dam crest elevation is 508 meters above sea level, while the riverbed elevation at the dam axis is 386 meters above sea level. Notably, 80 meters of the dam's height have been completed thus far. This article presents an analysis of pore pressure changes, pore pressure coefficient (Ru), vertical deformations, and the simultaneous effects of arching and settlement based on international standards. The insights drawn from this investigation contribute to a deeper understanding of the Haraz Dam's structural behavior and aid in refining construction strategies for enhanced safety and performance.
