摘要
以南京地铁奥—元区间基坑围护结构为例,介绍了钻孔桩与深搅桩复合式支护体系在地铁明挖深基坑的应用.采用弹性杆系有限元法对支护体系的内力及变形进行了分析,其中用同济大学的启明星基坑设计软件计算其内力及变形值,并与实际监测值进行比较和分析.
Taking the base pit supporting structure in Nanjing subway as an example, this paper introduces the application of compound supporting system with drilling stake and deep stirring stake in deep base pit of subway ,and analyzes the internal force and deformation of supporting system as well.
