摘要:
为了分析京沪高速铁路CRTSⅡ型板式无砟轨道结构的动力响应,通过建立无砟轨道结构-下部基础结构动力有限元分析模型,得到了结构前10阶模态和不同列车速度下无砟轨道结构的动力特性.分析结果表明:桥梁上CRTSⅡ型板式无砟轨道结构的自振频率都比规范的限值大,说明桥梁有足够的刚度保证列车行驶的安全性和舒适性;桥梁上板式无砟轨道结构的前10阶振型中大部分振型表现为横向扭转,桥梁结构横向刚度相对较小,在实际的高速铁路桥梁结构中应注意桥梁的横向稳定性;无砟轨道结构各个构件的竖向位移、竖向加速度、板底水平拉应力及CA砂浆层竖向压应力均随列车速度的增大而逐渐增大;线下基础结构顶面竖向压应力存在转折变化点.
Abstract:
In order to research the dynamic response of the ballastless track slab structure of Beijing-Shanghai High-Speed Railway,China railway track slab(CRTS)Ⅱstructure with the supporting part is built based on the composite solid element theory, obtaining first ten modals and dynamic characteristics at different speeds. The analysis results show that the natural frequency of CRTSⅡ slab track on the bridge is larger than the specification limit, and, therefore, the bridge has sufficient rigidity to ensure the safety and comfort; as the first ten modals of the slab track on the bridge structure is lateral torsion, the lateral stiffness of the bridge structure is relatively low, so the lateral stability of the bridge should be noted; the vertical displacement, vertical acceleration, and bottom horizontal tensile stress in each component of the ballastless track structure(BTS)and the vertical stress of the concrete asphalt(CA)mortar layer are gradually increased with the increasing speed of the trains; the vertical stress of the top surface under line infrastructure has a turning point.
