    Default 网球场

    国际网联和国家体委颁布的《网球竞赛规则》中规定,一片标准网球场地的占地面积不小于36.58米(长)×18.29米(宽),这个尺寸也是一片标准网球场地四周围挡网或室内建筑内墙面的净尺寸。在这个面积内,有效双打场地的标准尺寸是:23.77米(长)&# 215;10.97米(宽),在每条端线后应留有空余地不小于3.66米。在球场安装网柱,两柱中心测量, 柱间距离是12.80米。网柱顶端距地平面是1.07米,球网中心上沿距地平面是0.914米 。   如果是两片或两片以上相邻而建的并行网球场地,相邻场地的边线之间距离不小于4米。   如果是室内网球场,端线6.40米以外上空净高不小于6.40米,室内屋顶在球网上空的净高不小于11.50米。室外网球场 首先要考虑的问题:1)日照问题:为了避免日光弦目,室外网球场走向多为南北走向,如果周围有建筑物遮蔽,可另行别论。2)降雨排水问题:为了保证在最短时间内恢复场地的 正常使用,国际网联规定,室外场地的散水坡为横向,坡度不大于8‰。   室外网球场地的四周围挡网高度一般在4-6米之间,视球场周围环境与建筑物高度,也可适量增减。需要安装照明灯光的网球场,除室内屋顶灯具分布外, 室外球场上空和端线两侧不应设置灯具。室外球场灯具应设置在两侧围挡网距地面高7.60米以上,灯光从球场 两侧场面均匀照射。   灯光照度应当根据球场使用的不同用途,请电光源技术人员专门设计。体育工程经验告诉我们,每片网球场照光的平均照度,应当在600个勒克斯以上。
