基于Gunary模型的侧限条件下土体结构性参数研究
Study on Soil Structural Parameters under Confined Compression Condition Based on Gunary Model
摘要
Abstract
The study of soil structural parameters is an important and difficult research content in geotechnical engineering.Some stress-controlled and strain-controlled confined compression tests are carried out to investigate soil structural parameters.The new stress-strain relation representing formula,the Gunary model,and the secant modulus method are used.A simplified and applicable single variable soil structural parameter model under confined condition has been given.Based on the comparison between laboratory tested values and calculated values,the authors prove the strain-considered structural parameter calculated values with stress,and the stress-considered structural parameter calculated values with strain separately conform to the quadratic polynomial and the two-parameter linear reciprocal function form,and demonstrate the rationality of the Gunary model to study soil structural parameters.关键词
