摘要：【中文】本发明涉及一种上承式阻尼支承块及连续支承轨道系统与施工方法，通过在既有的无砟轨道扣件之间安装钢轨阻尼支承块，将非连续支承轨道系统改造为连续支承轨道系统，阻尼支承块具有与轨底适形匹配的轨底凹槽以及与轨腰侧面适形匹配的轨腰对应面；钢轨悬空段由内、外侧阻尼支承块支承。本发明可对传统扣件非连续支承轨道系统的动力特性进行改善，可有效提高减振降噪性能，减小短波不平顺，利于减小轮轨磨耗，延长轮轨寿命；使用本发明可使大量的城轨地铁小曲线半径钢轨短寿命状态可得到极大改善，能极大减少更换钢轨的维修工作量，延长小曲线钢轨的使用寿命，利于减小运维成本，提高运营经济效益和提高乘客舒适度。 【EN】The invention relates to a top bearing type damping supporting block, a continuous supporting track system and a construction method, wherein a steel rail damping supporting block is arranged between existing ballastless track fasteners, the discontinuous supporting track system is transformed into the continuous supporting track system, and the damping supporting block is provided with a rail bottom groove matched with a rail bottom in a shape-fitting manner and a rail waist corresponding surface matched with a rail waist in a shape-fitting manner; the rail suspension section is supported by inner and outer damping support blocks. The dynamic characteristic of a traditional fastener discontinuous support track system can be improved, the vibration and noise reduction performance can be effectively improved, the irregularity of short waves is reduced, the abrasion of wheel rails is reduced, and the service life of the wheel rails is prolonged; the invention can greatly improve the short-life state of a large number of urban rail subway small-curve-radius steel rails, greatly reduce the maintenance workload of replacing the steel rails, prolong the service life of the small-curve steel rails, facilitate the reduction of operation and maintenance cost, improve the operation economic benefit and improve the comfort level of passengers.
