| 摘 要： | 1 IntroductionFreezing reinforcement technology has beenapplied more and more in municipal engineeringcurrently. Especially in recent years the technology ofreinforcing soil mass in big diameter (Φ >10 m)shield launching has become one of crucialtechnologies of tunneling. Comparing with routinestir stake, grouting and revolving spray etc, it hasmore advantages. The frozen wall is much moreuniformity, higher strength and better water closed .Itis efficient consolidate technology to the large …

| Abstract: | Aimed at the frozen soil arch reinforcement form of upside shed used for the shield machine launching in tunneling the internal force of the structure was calculated with the aid of the structural mechanics theory. Considering the space characteristics of the structure, this calculating method is suitable for practical engineering. Moreover, the behavior of the freezing arch reinforcement structure was analyzed combined with an engineering case. |
