在无碴轨道结构设计中应考虑基础变形对轨道结构的受力影响,提出桥梁挠曲变形和路基不均匀沉降对轨道结构受力的计算方法和计算公式。桥梁的挠曲变形应作为设计荷载附加到轨道结构的设计中,路基的不均匀沉降应作为异常荷载,在轨道结构设计中作为检算荷载进行考虑。
In the ballastless track structure design, the influence of foundation deformation on the track structure should be considered. The calculation method and calculation formula for the stress on the bridge structure by the deflection of the bridge and the uneven subgrade settlement are proposed. The deflection of the bridge should be added as a design load to the design of the track structure. The uneven subsidence of the subgrade should be considered as anomalous load and considered as the checked load in the design of the track structure.
