本文根据大量粗粒土三轴压缩试验成果,分析研究了粗粒土的应力应变特性及变化规律,对邓肯E-μ模型的参数式作了较大的改进,并提出了新的参数关系式。
In this paper, according to the results of triaxial compression tests on a large number of coarse-grained soils, the stress-strain characteristics and the changing rules of coarse-grained soils are analyzed and analyzed. The parametric formula of Duncan E-μ model is greatly improved, and a new parameter relationship is proposed. .
