摘要
双护盾TBM受自身工法特点制约,在实际应用中遇到不良地质后会造成不同程度的卡机.以南亚某国引水隧洞施工为例,对双护盾TBM在软弱围岩中被卡脱困处理情况进行介绍和分析,提出卡机脱困处理的方法和措施.
Abstract
Restricted by the characteristics of its own construction method,stuck machine in different degrees after encountering bad geology in practical application will occur in the double shield TBM.Taking the construction of diversion tunnel in a country of South Asia as an example,this paper introduces and analyzes the treatment of double-shield TBM stuck in weak surrounding rock,and puts forward the methods and measures for the treatment of stuck TBM.
