摘要通过采用刚性模型风洞测压实验,本研究旨在探讨两个具有不同高度的干煤棚受到不同风向影响时的荷载变化情况。经过对0°、180°、45°、135四种不同风向的影响因素的对比研究,我们发现,不同的风向对高干煤棚和低干煤棚的影响有着显著的差异。根据最新的研究结果,在上游的高干煤棚中,风的作用力明显较弱,而在下游的低干煤棚中,风的作用力明显较强。在45的风向角度下,低干煤棚处在水流的下游,但是上升的风力却明显地随着水流的方向发生了改变。该文介绍了建筑工程中常用的一些术语,包括高低双干煤棚、风洞试验、风荷载和体型系数。高低双干煤棚通常用于煤炭储存,在建造过程中需要考虑结构强度,以及避免受到风荷载等外部因素影响。风洞试验是模拟空气流动的一种实验方法,用于研究建筑结构在不同风速和风向下所受到的风荷载及其他气动力学特性。风荷载是建筑结构在面对风力时所受到的作用,需要对建筑材料的强度、结构的稳定性等进行充分评估。体型系数是描述流体运动中物体所受到阻力的一种参数,它可以通过计算阻力和气体密度、速度等参数来确定。这些概念和术语在建筑工程和流体力学中起到了重要的作用。对比多个国家及地区的规范对于建筑结构承受风荷载计算方法。关键词:高低双干煤棚:风洞试验:风荷载:体型系数AbstractAbstractTo study the wind load characteristics and variation rules of mutual interferencebetween high and low dry coal sheds under different wind directions,a method of rigidmodel wind tunnel test was adopted.By comparing the body shape coefficients at 0 and180 wind directions and 45 and 135 wind directions,the variation rules of body shapecoefficients when high and low dry coal sheds interfere with each other were analyzed.The results showed that the wind suction force on the top of the high dry coal sheddecreased when it was upstream,while the wind suction force on the top of the low drycoal shed increased when it was upstream.At a wind direction of 45,the low dry coalshed was downstream,and the wind suction force on the top varied significantly along thevertical axis.This paper introduces some common terms and concepts used in constructionengineering and fluid mechanics,including high and low double dry coal sheds,windtunnel tests,wind loads,and body shape coefficients.High and low double dry coal shedsare commonly used for coal storage,and need to consider structural strength and avoidexternal factors such as wind loads during construction.Wind tunnel tests simulate air flowand are used to study the aerodynamic characteristics of building structures under differentwind speeds and directions.Wind loads are the forces that building structures face whenfacing wind,and require full evaluation of the strength of building materials and thestability of the structure.Body shape coefficients are parameters that describe theresistance experienced by a body during fluid motion,and can be determined bycalculating parameters such as resistance,gas density,and velocity.These concepts andterms play an important role in construction engineering and fluid mechanics.The paperalso compares the calculation methods of wind load bearing capacity for buildingstructures in different countries and regions.Keywords:high and low double dry coal sheds;wind tunnel test;wind load;body shapecoefficient第1章绪论1.1研究背景自第一次工业革命以来,全球经济和技术的飞速进步为世界带来了巨大的变化。煤炭是工业的基础,因此人们对它的储存方式也非常关注。储煤技术从露天到封闭,从二维结构到空间结构,不断发展和演进。随着现代生活的发展,大跨结构已成为不可或缺的一部分,它不仅满足了二维、三维以及造型反面的要求,这个话题引起了全球建筑界和学术界的高度重视,并且得到了广泛的研究和探讨。随着人们对能源和基础设施的需求日益增加,大型储存设备已经在电力、煤炭、水泥等行业发挥出了重要作用,取得了显著的成就。例如,干煤棚能够防止雨水侵蚀并保护环境。由于它们之间存在着相似的特征,因此我们将它们统称为大跨结构。随着日益加强的环境保护意识,政府采取了更加严格的土地管理措施,以阻止煤炭的进一步排放,减少由于气候变化导致的煤的品质下降和损耗,传统的储存方式已经不能满足需求,因此,中国的储煤仓技术发展迅猛,已经开始大规模应用。储煤仓具有宽广的跨度、高度和覆盖面积,使其成为一种理想的储存设施。随着中国改革开放的深入推进,电力工业
