Planning method for double-layer frame pier of oblique crossing line of railway
The invention discloses a planning method for a double-layer frame pier of a railway skew line. The planning method comprises the following steps that loads of an upper-layer box girder and a lower-layer box girder are determined; determining load action positions of the upper-layer box girder and the lower-layer box girder; determining the resultant action point of the upper and lower railway box girders; determining the center line position of a double-layer frame pier beam; determining the minimum width of a frame pier cross beam; and completing the design of the skew line. According to the planning method for the double-layer frame pier of the oblique crossing railway, the out-of-plane effects of the upper-layer oblique crossing railway and the lower-layer oblique crossing railway on the double-layer frame pier can be basically symmetrical, and the torsion stress of the structure is reduced. According to the planning method for the double-layer frame pier of the oblique crossing railway, the width of the cross beam of the double-layer frame pier of the oblique crossing railway can be reduced, or arrangement of tooth blocks is avoided, construction is facilitated, and investment is saved.
本发明公开了一种铁路斜交线路双层框架墩的规划方法，包括以下步骤：确定上层箱梁和下层箱梁的荷载；确定上层箱梁和下层箱梁的荷载作用位置；确定上、下层铁路箱梁合力作用点；确定双层框架墩横梁中心线位置；确定框架墩横梁最小宽度；完成斜交线路的设计。本发明提出铁路斜交线路双层框架墩的规划方法，能够使上下层斜交铁路对双层框架墩平面外作用基本对称，减小了结构的扭转受力。本发明提出的铁路斜交线路双层框架墩的规划方法，能够减少斜交铁路双层框架墩的横梁宽度，或避免设置齿块，方便了施工，节省了投资。
