摘　　要：基于欧拉-欧拉方法,依托数值模拟平台,对大跨度椭圆形双曲屋盖结构进行干扰效应的风驱雨压分布特性研究。在施扰建筑的干扰作用下,通过控制两建筑之间的不同高度差、不同间距、不同风速,研究大跨度椭圆形双曲屋盖表面风驱雨压分布特性规律。随着两建筑之间的高度差增大,屋盖表面压力系数值减小,当高度差为0时,目标建筑的屋盖所受到的压力最大;两建筑之间的间距对屋盖表面风压有一定的影响,迎风前缘的一部分屋盖受吸力作用,其他区域均为压力作用;风速对屋盖两侧的压力影响较大,屋盖两侧所受到的压力随着风速增大而增大,且屋盖纵向两端的压力最大。Based on Euler-Euler method and numerical simulation platform,the distribution characteristics of wind-driven rain pressure of large-span elliptical hyperbolic roof structure considering interference effect are studied.Under the interference of the interfering building,by controlling the height difference,different spacings and different wind speeds between the two buildings,the distribution characteristics of wind-driven rain pressure on the surface of large-span elliptical hyperbolic roof are studied.The results show that as the height differences between the two buildings increase,the pressure coefficient of the roof surface decreases.When the height difference is 0,the pressure on the roof of the target building is the largest.The distance between the two buildings has a certain influence on the wind pressure of the roof surface.A part of the roof on the windward leading edge is subjected to suction,and the other areas are subjected to pressure.The wind speed greatly influences the roof side pressure.With the increase of wind speed,the pressure on both sides of the roof increases,and the pressure on both ends of the roof is the largest.
