ABSTRACT
This paper presents aspects of the Construction, Monitoring, Instrumentation, Monitoring and Modeling of the Masjed-E-
Soleiman Dam. This marvel of hydro-electric dam infrastructure, with a central clay core and a maximum height of 176 m, was constructed on the Karun River, Khuzestan, Iran. It consists of a 480 m long crest and the total volume of the clay dam body measures 13,000,000 m 3 . The paper summarizes the main construction and monitoring considerations for the dam itself as well as relevant factors associated with dam design and performance. The monitoring plan for the dam was intended to assist in the evaluation of the performance relating to seepage and leakage, and deformation due to: slope instability, settlement, consolidation of fill, consolidation of foundation strata, secondary consolidation of fill and foundation, volume change in clay, changes in reservoir levels and seismic disturbance. Further, the paper summarizes the total stresses and pore water pressure in the clay core of the dam during the construction up until the end of construction, just prior to the filling of the reservoir through the use of monitoring data captured in-situ. These monitoring results have been amassed and consolidate in this report and were used as validation data for a finite element model that was created for this purpose. As such, the numerical model developed can be used to predict long time behavior and progress of consolidation of the dam’s core. Moreover, it can be used to model the long-term deformations resulting from the consolidation progress.
