The loading history and interaction of theconstruction with ground settlements, earthquake activities andflooding, chemical reactions with water, overtopping, and thestate of weathering and aging of the construction material mayplay an important role in the safe operation of hydraulicstructures such as earth, rockfill, and concrete dams, as wellas novel reinforced soil structures. A critical reduction ofthe safety of dams can be caused by the evolution of internalerosion, cracks in the sealing, earthquake-induced deformations,reduction of the slope stability of earth and rockfilldams triggered by heavy rainwater infiltration, or rapid reductionof the water level in the reservoir.展开更多
