摘要
由于土钉支护的复杂性,其作用机理和设计理论仍处于研究阶段。根据土钉作用机理,研究了钉土的本构关系,建立了土钉的破坏准则、开挖荷载与位移计算有限元模型及模拟过程,并通过算例、试验,验证了数值计算在土钉设计中的可靠性,为土钉支护设计提供了依据。
The mechanism and design of soil nailing suppport is in a stage of study due to its complexity. Based on the mechanism of soil nailing the constitutive relation was studied, the failure criteria, excavation load and displacement calculation FEM model and simulation process of soil nailing have been setup, the reliability of numerical calculation in soil nailing design is verified by example, test, which can provide base for soil nailing support design.
