盾构管片力学性能及抗渗性试验

摘要

This paper introduced the basic situation of imflexural test and impermeability test method of SDⅡ duct piece of Guangdong-Shenzhen-HongKong passenger transportation line Shiziyang tunnel,compared and analyzed the differences of stress conditions or permeate situation in duct piece test and the actual stress conditions or permeate situation in construction process,so as to prove the feasibility of this modified test method.%介绍了广深港客运专线狮子洋隧道SDⅡ标管片的抗弯试验及抗渗性试验方法的基本情况,对管片在试验过程中的受力状况或受渗情况与其在隧道土体中及在施工过程中的实际可能的受力情况或受渗情况之间的差异进行了比较分析,从而证明了该试验方法的可行性。
