摘　　要：大连梭鱼湾足球场(简称梭鱼湾足球场)总建筑面积13.6万m~2,坐席6.3万座。足球场罩棚支承于混凝土看台顶部。罩棚结构为上弦斜交索系-下弦放射状索系,平面为四心圆的索桁架结构。相比常规的轮辐式索桁架结构,该体系具有更强的面内刚度和整体抗扭能力。对罩棚结构进行了形态分析,计算了其动力特性及抗连续倒塌;建立了摇摆柱支承的单压环梁的设计方法,并计算了其承载力与稳定性;设计了跨度超过30m的索系支承膜结构;介绍了上弦斜交索系上环索索夹节点,其串联式的索夹盖板连接键的设计,提高了环索索夹的抗滑移承载力。结果表明上弦斜交索系-下弦放射状索系索桁架结构体系合理。Dalian Suoyuwan Football Stadium(referred to as the Suoyuwan Stadium)has a total construction area of 136000m2 and can accommodate 63000 spectators.The roof of the stadium,supported on top of the concrete bowl,is a cable truss structure with upper chord oblique cable system and lower chord radial cable system.Compared to the traditional spoke cable truss structure,this system offers enhanced in-plane stiffness and overall torsional resistance.The form-finding analysis results of the roof was introduced,its dynamic characteristics and collapse resistance were calculated.A design method was established for the pendulum columns that support a single compression ring beam,its bearing capacity and stability was calculated.The cable supporting membrane structure with span over 30m was designed.Additionally,the connection node design of upper tension ring was introduced,the connecting key of the cable clamp cover plate was designed to improve the anti-slip bearing capacity of the cable clamp.The results show that cable truss structure with the upper chord oblique cable system and lower chord radial cable system is reasonable.
