盾构进出洞土体稳定性力学模型及施工控制

The mechanical model and construction control of the shield tunnel portal and export soil stability

根据盾构进出洞工序是盾构隧道的关键工序,总结了进出洞段土体稳定性力学分析模型,归纳了盾构进出洞施工方法和控制技术要点,并通过进出洞技术措施的实施,从而保证了施工质量。

According to the portal and export process were typical process of shield tunnel, the mechanical analysis model of soil stability in portal and export section were generalized, the construction methods and control technical points of shield portal and export were inducted. Through practice of portal and export technical measures, the construction quality was guaranteed.
