考虑沉桩应力路径的桩周土三轴试验研究

In this paper, constitutive relation of soil is obvious contribution by the stress path and stress history, so deformation characteristic of soil around pile which is considering the stress path of pile-sinking is a topic of geotechnical engineering that many students concern about. This paper introduces an test method simulating stress path of pile-sinking to study the law of soil deformation around pile, which is using GDS triaxial test instrument, and makes a discussion and generalization at the same time.
