系杆拱桥是集桥梁和拱形优点于一身的完美契合物,桥梁与拱在这种组合中共同承受分担着整个桥梁的承载力和弯拱压力,拱端的水平推力用拉杆承受,使拱端支座不产生水平推力。文章以南水北调中线工程新郑南十里铺东南公路桥为例,对系杆拱桥的钢管拱肋制作作浅要分析,为工程建设积累施工经验。
Tied arch bridge is the perfect combination of the advantages of the bridge and the arch, the bridge and the arch in this combination to bear the load bearing capacity of the bridge and the arch pressure, the arch end of the horizontal thrust with the lever to withstand the arch end Support does not produce horizontal thrust. Taking South Xin Shonan Shiliubu southeastern highway bridge as an example, the paper analyzes the production of steel pipe arch rib of tied arch bridge and accumulates construction experience for the project construction.
