摘　　要：结合青岛市火车站改造工程,运用FLAC3D对预应力锚杆+土钉的复合支护的开挖与支护全过程进行了数值模拟,对比分析了不同工况下基坑位移变形和支护结构的内力变化,并对复合土钉支护的作用机理进行了分析。Based on the project of Qingdao railway station, the article makes numerical simulation course of excavation and support of the composite soil nailing by the Way of using FLAC3D software, of the displacement of foundation pit and inner force variation of supporting structure in the different conditions, and mechanism analysis of the composite soil nailing.

关 键 词：复合土钉支护 FLAC3D 基坑位移变形 作用机理
