摘　　要：上海科技馆屋面是螺旋型半圆旋转屋面,屋面防水改造工程是本项目改造的重点,主要是将原来的平面结构铝板屋面改成防水功能更完善的直立锁边结构铝镁锰合金屋面。改造后的屋面结构给屋面排水带来两个难点:是否存在雨水从一块直立锁边翻越到下游另一块直立锁边的情况,上游的雨水是否会越过外弧天沟流入下游,造成下游内弧天沟超负荷排水。项目组通过水力学理论分析计算和水力试验两种方法验证上述两个关键问题,并对上海科技馆屋面防水维修工程提供建设性建议。The roof of Shanghai Science and Technology Museum is a spiral semi-circular rotating roof,and the waterproofing renovation project is the focus of this project.The main goal is to replace the original flat structure aluminum sheet roof with a more complete vertical locking edge structure aluminum magnesium manganese alloy roof with more waterproof functions.The renovated roof structure brings two difficulties to roof drainage:First,whether there is a situation where rainwater flows from one vertical locking edge to another downstream vertical locking edge.And second,whether upstream rainwater will cross the outer arc gutter and flow downstream,causing overload drainage of the inner arc gutter downstream.The project team verified the above two key issues through two methods:hydraulic theory analysis,calculation,and hydraulic testing,and provided constructive suggestions for the roof waterproofing maintenance project of Shanghai Science and Technology Museum.
