摘要
本文针对复杂艰险山区高速铁路桥梁设计中的主要技术问题,结合相关科学研究和实践经验,提出了高速铁路高墩大跨桥梁跨径范围和选型原则,提出了高烈度地震区桥梁设计和减隔震技术,提出了峡谷风环境下高速铁路行车安全保障技术。同时,对复杂艰险山区高速铁路桥梁设计中常见的高陡边坡防护、危岩落石防护以及泥石流综合治理等关键技术进行了总结,提出了相应的设计原则和解决方法,为复杂艰险山区高速铁路桥梁设计提供了重要的技术支撑。
For the main technical problems in the design of high-speed railway bridge in complex and dangerous mountainous area,combined with relevant scientific research and practical experience,this paper puts forward the span range and type selection principals of high-speed railway bridge with high piers and large spans,the technologies for design,and seismic reduction and isolation of the bridges in high-intensity earthquake areas,and the traffic safety guarantee technology of the high-speed railway in the canyon wind environment.And it summarizes the common key technologies in the design of high-speed railway bridge in complex and dangerous mountainous areas,such as high and steep slope protection,rockfall protection and comprehensive treatment of debris flow,and proposes the corresponding design principals and solutions,which provides the important technical support for the design of high-speed railway bridge in complex and dangerous mountainous area.
