盾构机铰接密封承载能力试验研究

摘要

The principle and structure of the shield’s articulation seals system were introduced in this paper,and the pres-sure action underground of the shield’s articulation seals system and its failure causes were analyzed.The test of pressure bearing performance for the failure and the quantization reference value for the sealing capability of the articulation seals system were provided.Lastly,the test results were analyzed and the optimization suggestions were provided.%首先介绍了盾构铰接密封系统的原理与结构，并分析了在受土层压力下盾体的受力情况和铰接密封失效原因。针对盾构铰接密封失效现象对密封系统样本进行了压力承载性能试验，并得出铰接密封系统密封性能的量化参考标准值。最后，对试验结果进行了分析并提出了优化建议。
