二、加筋土理论研究(一)边界条件,变形条件对塑性区形状和应力状态的影响。局部塑性平衡状态可以因不同变形的过程而产生。塑性区域内的应力状态和这区域本身的形状在很大程度上取决于变形的类型和土壤与侧文撑接触面的粗糙程度。这些因素构成了变形条件和边界条件。此外,加筋土自身如墙高,填料的物理力学性质,筋条的材质、长度、粗糙度及加筋密度等,这些因素构成了加筋土的内部条件。
Second, reinforced earth theory (a) boundary conditions, deformation conditions on the plastic zone shape and stress state. Local plastic balance can be due to different deformation process. The state of stress in the plastic zone and the shape of the area itself depend very much on the type of deformation and the roughness of the contact surface between the soil and the side brace. These factors constitute the deformation conditions and boundary conditions. In addition, the reinforced soil itself, such as wall height, the physical and mechanical properties of filler, rib material, length, roughness and reinforcement density, these factors constitute the internal conditions of reinforced soil.
