An infinity pool原义为无限空间的游泳池。就是没有边框视觉效果的游泳池。泳池与景色融合，达到独特的视觉效果。简单来说，即通过对泳池边缘的特殊设计，让游泳池看起来没有边缘与池壁，从而达到空间无限的视觉效果。

An infinity pool is a reflecting or swimming pool, where the water flows over one or more edges, producing a visual effect of water with no boundary. Such pools are often designed so that the edge appears to merge with a larger body of water such as the ocean, or with the sky. They are often seen at resorts, estates, and in other luxurious places.

It has been claimed that the infinity pool concept originated in France, and that one of the first vanishing-edge designs was the Stag Fountain at the Palace of Versailles, built in the late 17th century. In the US, architect John Lautner has been credited as one of the first to come up with an infinity pool design in the early 1960s. He included infinity pools in various residential projects, and also created the vanishing-edge pool in the James Bond movie Diamonds Are Forever (1971).

Infinity pools are very expensive and require extensive structural, mechanical, and architectural detailing.Since they are often built in precarious locations, sound structural engineering is paramount. The high cost of these pools often arises from the elaborate foundation systems that anchor them to hillsides.

The “infinite” edge of the pool terminates at a weir that is 1⁄16 to 1⁄4 inch (2 to 6 mm) lower than the required pool water level. A trough or catch basin is constructed below the weir. The water spills into the catch basin, from where it is pumped back into the pool.
