本文论证了横向分块予应力钢筋混疑土梁用于铁路桥跨的意义和技术经济指标;回顾了世界各国应用横向分块桥梁的情况及横向分块梁的构造型式和结构细节。文中着重叙述具有竖直平接缝及贯穿式钢丝束的横向分块梁的模型试验结果。最后提出设计和安装横向分块予应力钢筋混凝土铁路桥跨的意见。
This paper demonstrates the significance and technical and economic indicators of laterally stressed prestressed reinforced skeletal soils for railway bridges and bridges. It also reviews the application of transverse segmented bridges in various countries in the world and the structural type and structural details of transverse segmental beams. This paper focuses on the model test results of transverse block beams with vertical flat seams and through steel wire bundles. Finally, the author puts forward the suggestion of designing and installing transverse block to prestressed reinforced concrete railway bridge span.
