作为抽水蓄能电站进出水口与库岸公路连接的交通桥,桥墩通常不可避免的置落于库岸岸坡上,导致桥墩高度的差异,这对于连续钢构桥来说,将带来桥梁设计上的特殊性。本文主要探索高矮墩连续刚构桥在结构受力、地震响应、施工预拱度设置、合龙技术等设计过程中面临的问题的特点、难点及不同,并提出了相应的处理对策,为同类型桥梁设计提供参考作用。
As a traffic bridge connecting the inlet and outlet of the Pumped Storage Power Station to the reservoir bank road, piers are usually placed inevitably on bank bank slopes, resulting in differences in piers height, which will bring about bridge design for continuous steel bridges On the particularity. This paper mainly explores the characteristics, difficulties and differences of the problems encountered in the design process of the tall short pier continuous rigid frame bridge in the process of structural stress, seismic response, construction camber setting, closing technology and so on, and puts forward the corresponding treatment measures for the same type Bridge design provides a reference.
