Abstract

Karkheh dam cut-off wall with an area of about 150000 m2 is the largest plastic concrete cut-off wall ever built in the world. The wall was designed on the basis of seepage and material behavior analysis. The design and construction of the wall was a great challenge in which in different stages, major design modifications were made based on existing construction facilities, updated geological conditions and cost optimization. The philosophy of “design as you go” was tried to be perfectly accomplished in this project. The cut-off wall connections to the dam body and other appurtenant structures such as power tunnels; diversion culvert and spillway were designed and constructed to provide a tight and deformable interface. In this paper, the analysis results are briefly described. The technical specification of execution and material is also summarized.

Karkheh Storage Dam Cutoff Wall Analysis and Design

New York, New York

Karkheh dam cut-off wall with an area of about 150000 m2 is the largest plastic concrete cut-off wall ever built in the world. The wall was designed on the basis of seepage and material behavior analysis. The design and construction of the wall was a great challenge in which in different stages, major design modifications were made based on existing construction facilities, updated geological conditions and cost optimization. The philosophy of “design as you go” was tried to be perfectly accomplished in this project. The cut-off wall connections to the dam body and other appurtenant structures such as power tunnels; diversion culvert and spillway were designed and constructed to provide a tight and deformable interface.
