摘要
通过分析研究桥式盾构法下穿路基工程,总结得出桥式盾构法下穿路基变形的关键影响因素,并深入分析其变形机制。根据提出的关键影响因素,依托实际工程,进行桥式盾构下穿既有高速公路和结构的设计应用,提出了多种应对既有路基和结构变形的设计。
By analyzing and studying the projects of bridgeshield method undercrossing subgrade,the key influencing factors onthe deformation of bridgeshield method undercrossing subgrade are summarized,and the deformation mechanism is deeply analyzed.According to the proposed key influencing factors and relying on the actual project,the design application of bridgeshield method undercrossing the existing expressways and structures is carried out.A variety of designs to control the deformation of existing subgrade and structure is proposed.
