小型工作装置的物理模拟试验台,其主试验台是一个土壤集装箱(内有土槽和介质、等量材料、土壤的容器)。为了在模拟(高强度的)冻土开挖过程中获得可靠的试验结果,必须在结构上保证土壤与集装箱壁和箱底接触面上的边界条件相似。为了保证受限制的土块模型的边界条件相 The physical simulation test rig of the small-sized working device has its main test rig is a soil container (with soil tanks and media, equivalent materials, soil containers). In order to obtain reliable test results during excavation of simulated (high-strength) frozen soils, it must be structurally ensured that the boundary conditions at the interface between the soil and the container wall and the bottom of the tank are similar. To ensure the boundary conditions of the restricted clod model
