| 摘 要： | 研究了影响冻结井预制弧板井壁变形特性的接头刚度.将接头垫层受力特性抽象为若干弹簧，通过力学平衡条件和合理的简化，建立了接头刚度理论模型；考虑到工程应用实际，推导了接头刚度工程实用简化公式；通过理论计算与试验结果的对比，验证了冻结井预制弧板井壁接头刚度模型的合理性.

| Abstract: | Studied the joint rigidity which affects deformation characteristics of prefabricated arc board of freezing well.The stress characteristics of joint cushion was abstracted to some spring,and the theoretical model of joint rigidity was built by mechanics equilibrium condition and reasonable simplification.Considering technical application practice,the engineering practical reduction formula of joint rigidity was derived.The contrast of theory calculation and test results verifies the rationality of joint rigidity model of prefabricated arc board of freezing shaft wall. |
