2019-05-04

1、人行道或安全带外侧的桥梁灯光护栏高度不应小于1.10m。栏杆构件间的净间距不得大于140mm,切不宜采用横线条栏杆。桥梁灯光栏杆结构设计必须安全可靠,栏杆底座应设置锚筋,其强度应满足国家规范要求。2、桥梁灯光护栏强度应满足:车辆以80KM/H的速度,与栏杆成15角发生碰撞,不落河。3、桥梁护栏造型、色调与周围环境协调,对重要桥梁宜作景观设计。4、当桥梁灯光护栏跨越快速路、城市隔离栏轨道交通、高速公路、铁路干线等重要交通通道时,桥面人行道栏杆上应加设护网,护网高度不应小于2m,护网长度宜为下穿道路的宽度并各向路外延长10m。5、作用在桥上人行道栏杆扶手上竖向荷载应为1.2KM/m;水平向外荷载应为2.5KM/m。两者应分别计算。
