摘要
考虑TBM施工隧道管片结构之间的橡胶垫对管片力学性质的影响,采用解析计算的力法,推导了橡胶垫和管片的环向受力与变形的解析表达式,建立了围岩压力与管片环向半径变化量之间的关系式。依托实际工程背景,研究了考虑橡胶垫作用的TBM隧道管片结构的环向变形性能,验证了推导公式的正确性。研究结果为TBM施工隧道的管片衬砌结构的变形性能提供理论基础。
Considering the influence of rubber gasket between segment structure of TBM construction tunnel on the mechanical properties of segment, the analytical expressions of circumferential force and deformation of rubber pad and segment are derived by using the force method of analytical calculation. The relationship between the surrounding rock pressure and the circumferential radius of the segment is established. Based on the practical engineering background, the circumferential deformation performance of TBM tunnel segment structure considering rubber cushion is studied, and the correctness of the derived formula is verified. The research results provide a theoretical basis for the deformation performance of segment lining structure of TBM tunnel.
