盾构法施工过程中,进出洞一直是一个工程难题.在此过程中,必须保证洞口土的稳定性,以及周边建筑的安全.文章以某河底公路隧道工程为例,从洞口地基加固和盾构进洞两大方面,就盾构隧道进出洞地基加固处理工艺展开详细研究,进行施工效果分析,研究成果可为类似工程提供参考.
Research on Foundation Reinforcement Treatment Process for Shield Tunnel Entrance and Exit
In the process of shield construction,the entry and exit of the tunnel has always been an engineering problem.In this process,the stability of the soil at the portal and the safety of the surrounding buildings must be guaranteed.Taking a river bottom highway tunnel project as an example,this paper makes a detailed study on the foundation reinforcement treatment process of shield tunnel entrance and exit from two aspects of portal foundation reinforcement and shield entry.Finally,the construction effect is analyzed.The research results can provide reference for similar engineering.
