【摘要】:为解决盾构隧道橡胶止水密封垫的数值分析难点,突破以工程类比法及经验法为主的密封垫防水性能设计的局限性,采用显式有限元分析方法对密封垫的压缩过程进行三维模拟,并将分析结果与力学试验对比,同时对影响橡胶密封垫力学性能的多种因素进行分析。主要得出以下结论:1)有限元模拟结果与试验结果具有一致性,验证了本文方法的有效性;2)对橡胶硬度和密封垫开孔率等因素进行分析,橡胶硬度越大,开孔率越低,则橡胶密封垫越硬,越难压缩。

3`2a HG H9I00引言目前,我国在建和已建的盾构隧道工程多采用预制管片拼装而成,管片间存在大量的环向接缝与纵向接缝,给盾构隧道的防水带来极大挑战。盾构隧道防水设计遵循“以防为主、多道设防、综合治理”的原则,在管片自防水的基础上,重点处理管片接缝防水[1]。在接缝处嵌入橡胶弹性密水利论文 T"@f;e9|'@9E
