The pillow-shaped sloping composite dam is a widely used type of dam characterized by a body that gradually widens from upstream to downstream, forming a shape resembling a pillow. Its structural design is relatively simple, consisting primarily of a dam foundation, the dam body itself, elastic elements, and impermeable barriers.
By adopting a sloping structural configuration for the dam body, the pillow-shaped sloping composite dam exhibits superior seismic resistance and sliding stability. Furthermore, this type of dam offers a certain degree of flow-throttling capability, which serves to mitigate the impact force of the water flow and reduce the hydrostatic pressure exerted on the dam body, thereby ensuring overall safety and stability.
During the construction phase, particular attention must be paid to the widening ratio of the dam body and to the selection of appropriate materials and thicknesses for the elastic elements. Additionally, rigorous anti-seepage measures must be implemented to prevent water leakage from compromising the structural integrity of the dam.
In summary, the pillow-shaped sloping composite dam represents an economical, practical, safe, and reliable type of dam. It is widely applied across sectors such as water conservancy and energy, playing a positive and instrumental role in fostering national economic development and social progress.
