摘要
合肥市轨道交通4号线下穿合福高速铁路蚌福联络线、合武绕行普速铁路,铁路运营对轨道变形及接触网杆等设施的变形要求严格,为保证盾构下穿施工时国铁的运营安全,文章利用Midasgts计算程序对盾构施工下穿国铁影响进行数值计算分析,并对盾构下穿国铁需采取的保护措施提出了建议。
Hefei metro line 4 crosses beneath Bengfu contact railway of Hefu High-speed railway and Hewu round railway.Railway operation requires strict deformation of track deformation and contact rod,the influences have been well analyzed based on the Midas gts software in this article,in order to ensure the safety of railway during shield tunnel construction,and the safeguard measures of shield tunnel construction crosses beneath railway were presented.
