摘要
围绕典型上软下硬地层的施工,分析了该地层中盾构法施工存在的问题和风险;为了提高上软下硬地层盾构施工掘进的效率,给出了施工的有效方法和措施;针对这种不良地层盾构施工发生的问题,研究了相应的应对措施,提高典型上软下硬地层的施工质量。
This paper mainly analyzes problems and risks of shield construction in typical stratum of soft layer under hard strata in order to improve the efficiency of shield tunneling in such stratum.The effective methods and measures of con-struction are put forward,and the corresponding measures are proposed to improve the quality of the construction in typical soft hard formation.
