摘要
防风明洞是大风区用于抵御风害影响的一种全新技术措施,其对大风区高速铁路建设具有较好的推广和应用价值。本文以防风明洞为主要研究对象,系统研究并分析了风速、地形、结构形式等因素对明洞结构所受风荷载及其分布特征的影响规律,明确了明洞结构所受风荷载分布特征及其数值大小。本文结论对大风区防风明洞结构设计具有较强的参考和指导意义。
Wind-proof tunnel in strong wind region is used to resist the influence of typhoon,it is a kind of new technical measures,for the high speed railway construction in the strong wind region it has good value of popularization and application.The wind-proof tunnel is the main object of study,it analyzes the impact of factors as wind,topography and structure form on wind load and its distribution characteristics of open cut tunnel,it determines wind loads distribution characteristics and numerical size subjected by the open cut tunnel structures.The conclusion of this paper has a strong reference and guiding significance to the design structure of the wind-proof tunnel.
