作者等在一定条件下对我国南方四省六种水田土样进行试验,初步提出以Burgers模型作为我国南方粘质水田土壤的通用模型,且认为流变系数只与土壤条件(机械组成、含水量、容量)有关,而与载荷条件(载荷值、承载面形状和面积)无关。根据上述原理,作者提出我国南方粘质水田土壤所表征的流变型土壤在一定土壤条件下的应力—应变—时间图,以及当应力在一定范围内时,流变曲线族在应力—应变—时间三维空间内舒展成流变曲面的概念。最后,作者提出了将此图应用于行走装置和切削元件研究的设想。
Under certain conditions, the authors tested soil samples of six paddy fields in four southern provinces in China. The Burgers model was first proposed as a general model of clay soil in southern China. The rheological coefficient was only related to soil conditions (mechanical composition and water content , Capacity), regardless of load conditions (load value, shape and area of bearing surface). According to the above principle, the authors put forward the stress-strain-time diagram of rheological soils characterized by clay soil in southern China under certain soil conditions, and when the stress is within a certain range, the rheological curve family in the stress-strain-time The concept of stretching into a curved surface in three dimensions. Finally, the author put forward the idea of applying this diagram to the research of walking devices and cutting elements.
