摘要

海岛山体地形下，低矮房屋在强风作用下受损严重，目前低矮房屋的抗风研究主要针对单体建筑，考虑周边环境影响的研究较少，关于山体地形下的低矮房屋风荷载受建筑群干扰效应的研究更是鲜有涉及。基于刚性模型测压风洞试验，对山坡地形下低矮房屋风荷载在受两个施扰房屋（位于试验房屋前方对称布置）干扰时的变化规律进行研究，讨论山坡间距和房屋高度的比值

S/H

= 0.2、0.4和1.0时，不同风向角下房屋表面平均风压分布和体型系数的变化规律。结果表明：当风向角为0°～90°时，

S/H

= 0.4的房屋墙面负压绝对值大于另外两种间距下的负压绝对值；当风向角为90°时，间距变化对墙面A和D的影响更明显；当风向角大于90°时，3种间距下的试验房屋的墙身约2/3以上区域受到较强风吸力作用。此外，依据《建筑结构荷载规范》（GB50009-2022）对试验房屋表面进行区域划分，各区域的最不利风向角为105°～150°，对应的体型系数均在

S/H

= 0.2时取得最小值，与规范值相比差异显著，且山坡地形对试验房屋的影响要大于前方的施扰房屋。

Abstract

Currently

there is still a significant lack of understanding regarding the effects of wind load on low-rise buildings situated in mountainous terrain

especially when considering the interference caused by building clusters. This paper presents a wind tunnel experimental study on the interference effects of wind load on low-rise buildings in mountainous landscapes

focusing on scenarios where two disturbance buildings are symmetrically positioned in

front of the test building. The distribution of surface average wind pressure and the variations of shape coefficients are discussed for the distance-to-height ratio

S/H

= 0.2

0.4

and 1.0 (

is the distance between a building with height

and the hillside) across a range of wind direction angle spanning from 0° to 180°. The results indicate that as the wind direction angle increases

the areas of wind suction on the surfaces of the experimental house expand. When the wind direction angle is between 0° and 90°

the absolute value of negative pressure on the wall with

S/H

= 0.4 is larger than that of the other two spacings. When the wind direction angle is 90°

the impact of spacing changes on walls A and D is more pronounced. When the wind direction angle exceeds 90°

the area with a wall height of about 2/3 or more of the test house is subjected to strong wind suction force

irrespective of the distance between the test house and the hillside. The surface of the test house is divided into more areas than standard buildings

and the obtained shape coefficients are significantly different from the specified values. The unfavorable wind direction angle is found to be in the range of 105°～150°

and the influence of the hillside terrain on the test house is more significant than that of the two buildings in its front. When the wind direction angle is 180°

the hillside first comes into contact with the incoming wind

but due to the influence of the hillside airflow

the absolute value of the test house's body shape coefficient decreases compared to its previous state. The shape coefficient of each area on the roof reaches its minimum value at

S/H

= 0.2 under the most unfavorable wind direction angle.
