摘要

摘要: 在双绞合六边形钢丝网加筋红砂岩粗粒土大型拉拔试验的基础上，分析双绞合六边形钢丝网筋材抗拔力的发展过程，研究采用理想弹塑性模型、双曲线模型和指数模型描述拉拔剪应力-位移曲线的不足，建立适合描述网状筋材筋土界面关系的幂函数模型，通过Fish函数对FLAC3D中Geogrid单元的筋土界面关系进行修正，并进行拉拔试验数值模拟，以验证筋土界面关系幂函数模型的可行性。

Abstract: Based on the large pullout test of double twisted hexagonal wire mesh reinforced coarse-grained red sandstone soil, the development process of mesh reinforcement's anti-pullout force was analyzed.After the deficiencies of ideal plastic material model, hyperbolic model, exponential model were studied when they were used to describe the pullout test's shear stress-displacement curve, the power function model which was fitting to described the mesh reinforcement's interaction relationship with soil was established, then the interface relationship of Geogrid in FLAC3D was modified by Fish Function and a numerical simulation of pullout test was carried out to verify the feasibility of power function mode.
