【摘要】 水泥乳化沥青砂浆充填层是CRTSⅠ型板式无碴轨道结构中重要的结构单元之一,是高速铁路的关键材料之一,起支撑、调平、吸振与减震的作用,其质量的好坏直接影响到板式无碴轨道结构的耐久性和列车运行的平稳性与安全性。因此选择对水泥乳化沥青砂浆充填层的质量控制为课题进行研究,具有十分重要的实际意义。水泥乳化沥青砂浆组成复杂,敏感性强,对其性能要求尤其严格。论文围绕CRTSⅠ型板式无碴轨道结构对水泥乳化沥青砂浆充填层的功能要求,结合目前水泥乳化沥青砂浆工程应用中存在的问题,就水泥乳化沥青砂浆材料特性与施工质量控制要点进行分析研究,提出运用全面质量管理理论的管理手段对砂浆充填层的质量进行控制。并以广州至珠海城际快速交通轨道ZH-3标为案例,具体阐述如何运用全面质量管理理论对砂浆施工质量进行控制。论文创新点为首次将全面质量管理理论运用到水泥乳化沥青砂浆质量控制中,为日后高速铁路无碴轨道水泥乳化沥青砂浆的建设提供一种思路和借鉴。更多还原

【Abstract】 Cement emulsified-asphalt mortar-filled layer constitutes an imperative part of CRTS I ballastless slab track and its material is of great importance in the construction of high-speed railway because it can support, level the rail and absorb shock as well; the quality of the material directly affects the durability of the ballastless slab track as well as stability and safety when a train is operated. Therefore, the research on the quality control of cement emulsified-asphalt mortar-filled layer is of great and practical significance.Cement emulsified-asphalt mortar boasts of complex composition and strong sensitiveness along with strict performance demands in particular. Based on the function requirements which CRTS I ballastless slab track imposes on cement emulsified-asphalt mortar, the thesis analyses special features of the mortar and studies the construction quality control according to current problems existing in the application of cement-emulsified asphalt mortar, furthermore it proposes that theory of total quality management should be used in the quality control of mortar-filled layer and elaborates on how to combine the theory and practice through taking the Guangzhou-Zhuhai rapid rail track ZH-3 as an example.The new idea of the thesis lies in that it brings the theory of total quality control to the practice of quality control of cement emulsified-asphalt mortar, which is unprecedented. It will provide a new clue and thinking pattern for the development of cement emulsified-asphalt mortar in the construction of high-speed railway ballastless slab track.更多还原
