| 摘 要： | 盾构管片接头弯曲刚度Kθ是盾构衬砌结构计算中的一个重要参数。根据管片接头构造特征，在传力衬垫和弹性密封橡胶试验资料的基础上，对管片接头进行受力分析，得到管片接头弯曲刚度与接头内力的非线性关系。为了应用方便，建立了实用的管片接头弯曲刚度的双直线模型。该接头刚度模型为梁一弹簧模型法和修正惯用法中的关键参数确定提供了基础，管片的内力计算也更加合理。

| Abstract: | Segment joint stiffness K? is an important parameter for the design of shield tunnel segment. Basing on the test data of load cushion and water-proof plastic, the joint’s mechanical characteristic has been analyzed and the nonlinear relation between the segment joint stiffness and joint’s internal force has also been obtained. In order to make convenient application for engineering, the article has established a bilinear joint stiffness model for shield segment joints. Because the model has provided the foundation to determine the key parameters of modified routine method and beam-spring method, calculation of shield tunnel segment becomes more rational. |
