ABSTRACT
Dam is a complex hydraulic structure having many components subjected to dynamic loads. Such components periodically manifest signs of distress and require repairs especially in case of aging dams. Conventional methods for repairs are mainly based on usage of impact resistant materials. As an alternative, solutions with geosynthetics are designed as impact resistant systems rather than depending merely on material properties. Such solutions not only help effectively repair the damaged components but also enhance their performance in several ways besides cost economy, faster execution and longevous life. The paper outlines main issues related to various dam components due to dynamic loads and presents case studies of aging Indian dams whose distressed components have been restored or are being restored with application of geosynthetics.
