gravity arch dam的意思|示意

Gravity arch dams are one of the most impressive and elegant of all dam types. They are constructed from two arches connected at the top and supported at both ends of the dam. The arches are designed to transfer the load of the water to the abutments at either end, and the arch itself acts as a cantilever beam which distributes the load more evenly than a traditional gravity dam.

Gravity arch dams are typically built on softer soils and weak rock foundations, which makes them able to better withstand the pressure of the water stored behind them. They are also designed to be cost-effective, as they require less materials and labor to construct than other types of dams. In addition, they often have a longer lifespan compared to other types, which helps to reduce long-term maintenance costs.

Gravity arch dams are also easier to inspect and maintain since the entire structure is contained within a relatively small area. This makes it easier to identify and address any problems quickly and efficiently.

Gravity arch dams can be used for various applications, including flood control, water supply, power generation, and irrigation. In addition, they offer controls over river levels and flows, and can serve as a deterrent to the spread of waterborne diseases.

Overall, gravity arch dams are a highly efficient and cost-effective type of dam. They are a great choice for many applications due to their durability and ability to withstand the pressure of the water stored behind them. With proper maintenance, they can provide many years of reliable service.
