随着我国不断推进体育建设的方针,体育强国建设不断深入,国家体育总局指出2035年足球将成为我国建成体育强国的标志性事业。由于人造草坪具有更耐磨、易打理、使用寿命长等优点,因此越来越多的足球场选用人造草坪来替代天然草坪来进行场地铺装。人造草坪分为免填充型人造草和填充型人造草。填充型人造草需要搭配一定填充比的石英砂和弹性颗粒,并配有弹性垫可以达到不同效果的运动性能,以匹配不同功能的足球场。本文探究了填充不同配比的石英砂和弹性颗粒对填充型人造草坪冲击吸收、垂直变形性能的影响。研究结果表明当配有弹性垫的人造草坪填充石英砂25kg/m2^,填充弹性颗粒8kg/m2^时,其运动性能较好。

With the continuous promotion of the policy of sports construction in China and the deepening of the construction of a sports power, the State Administration of sports pointed out that football will become a landmark cause of building a sports power in 2035. Because artificial turf have some advantages, including more wear- resistant, easy care and long service life, more and more football fields choose artificial turf to replace natural lawn for site pavement. Artificial turf is divided into non filling artificial turf and filling artificial turf. Filled artificial turf needs to be matched with quartz sand and elastic particles with a certain filling ratio, and equipped with elastic pads, which can achieve different sports performance to match football fields with different functions. The effects of filling different proportion of quartz sand and elastic particles on shock absorption and vertical deformation performance of filled artificial turf were investigated in this paper. The results showed that when the artificial turf with elastic pad is filled with 25kg /m2 ^{quartz sand and 8kg /m2} elastic particles, its sports performance is better.
