摘要
应用有限差分程序FLAC 3D分析土钉支护结构的地震稳定性,分析了地震作用下的土钉轴力响应规律,得出了弹性模量、粘聚力、内摩擦角3个土参数对坡顶某点的位移影响规律,为土钉支护边坡稳定的数值分析提供了借鉴.
The finite difference software FLAC3D is applied to analyse dynamic stability of soil nailing support structure;the effect regularity of modulus,cohesion and friction on sample displacement and regularity of soil nail axial force under earthquake is obtained,so as to provide for reference in numerical analysis of stability of soil-nailing support slopes.
