ICOLD Bulletin 150, Cutoffs for Dams, delves into the realm of foundation treatment methods utilizing cutoff-type barriers. While the focus primarily rests on alluvial deposits, it acknowledges that different materials may necessitate the use of cutoffs. The construction of cutoffs has witnessed remarkable advancements, driven by the development of more powerful machinery for drilling and excavation, as well as the introduction of innovative concepts and techniques like jet grouting and deep soil mixing. Presented within this Bulletin are various types of cutoffs:
- Diaphragm walls
- Vib walls
- Pile walls
- Superimposed concreted galleries
- Jet grouting
- Deep mixing
Each method is meticulously described, accompanied by selected case histories that showcase practical applications and the resolution of specific challenges encountered at particular dam sites. These case histories further illustrate the effectiveness of cutoffs in reducing flow and piezometric head. To evaluate the performance of cutoffs, it is crucial to monitor their efficiency by installing piezometers in the foundation upstream and downstream of the cutoff. These piezometers serve as vital tools in assessing the reduction in flow and the elevation change caused by the cutoff.
In conclusion, ICOLD Bulletin 150 provides a comprehensive exploration of foundation treatment methods using cutoff-type barriers. It emphasizes the importance of alluvial deposits, while recognizing the potential need for alternative materials. Through the development of advanced machinery, innovative techniques, and monitoring practices, cutoffs have become an effective tool in reducing flow and enhancing the stability of dams.
