摘要
根据土层锚固体锥形破坏模型、表面锚固型以及内部锚固型锚固体系研究的可转换性,推导出发生锥形破坏时锚固系统自由段长度表达式。运用ansys数值模拟,模拟不同锚固形式下锚固体-土体界面层,对比不同形式试验的ansys模拟结果。最后,通过模拟结果对比,验证试验以及推导的合理性,形成试验、理论以及数值模拟相结合的研究方法。
According to the soil anchor conical damage model, convertible research of surface anchorage and internal anchorage, the length taper expression of free section is derived when it comes to anchorage system conical damage. Using ansys numerical simulation, simulation different forms of anchor-soil interface layer, it compares ansys simulation results of different types of tests. Finally, with comparison of the simulation results and verifying the rationality of tests and deductions, it forms a study method of the combination of experiment, theory and numerical simulation.
