摘要:作为我国当时技术最先进的一条客运专线,秦沈客运专线作为我们此次毕业设计的课题,我们主要研究其路堤的设计方面和施工技术方面。另外,其在设计标准、施工技术、地基处理、工后沉降、路堤护坡等建造方面都采用创新的建造技术,它的建成标志着中国铁路步入高速化的铁路发展阶段,成为中国铁路的里程碑式的建筑。根据文献资料查阅,该线路大部分路段分布着大量的软粘土,因此对于工后沉降的施工控制是该线路地基处理和建造技术的重点,于是本次课题主要重点研究采用水泥土搅拌桩法和CFG桩法来控制工后沉降变形问题。秦沈客运专线在设计方面追求的创新,在施工技术方面追求科技化的高质量效益,在工后沉降上追求的严格要求等技术特点,对我国今后的高速铁路发展起到重大的指导意义。23582

Design and construction of embankment of Railway Passenger Dedicated Line
Abstract:Qin Shen passenger dedicated line is the first real significance of high-speed railway in China . Therefore, we have the graduation design mainly studies the embankment design and construction technology. In addition, its use of innovative construction technology in the design standards, construction technology, foundation treatment, settlement, embankment slope protection construction, it marks the completion of the Chinese railway into the high-speed railway development stage, become milepost type China railway construction. Check according to the literature, the line most of the distribution of a lot of soft clay, so as to control the construction of post construction settlement is the key of the line of foundation treatment and construction technology, and the paper mainly focuses on the cement soil mixing pile and CFG pile method to control the post construction settlement. The innovation of Qin Shen passenger dedicated line in the design of high quality benefit pursuit, the pursuit of science and technology in the construction of the technical aspects of the settlement after construction, in pursuit of the strict requirements and other technical characteristics, to the great significance to the development of high-speed railway in the future of our play.
Key Words:Embankment design;Foundation treatment;The settlement after construction
