侧限压缩条件下土体结构性参数的单变量模型
Single variable model of soil structural parameters under confined compression condition
摘要
Abstract
By analyzing the soil structural parameters based on strain considering and stress considering under confined compression conditions respectively, a unified expression for structural parameters is given, which is soil structural parameters using the secant modulus description. The obvious merit of the soil structural parameters expressed by the secant modulus is that it can avoid, when soil is under initial state, the soil structural parameters based on strain considering and stress considering can not be solved. Further, a single variable model of structural parameters using the active role description is established. In this model, the same stress method and strain method are utilized. For experiment, the confined compression test with intact sample, remolded sample and saturated intact sample from Yangling are conducted. Through the comparison of experimental values and calculation values, the rationality of the single variable model of structural parameters is tested. The results show that the calculated values agree with the experimental values well. The single variable model of structural parameters using the active role description can directly reflect the influence of the active role on soil structure. In addition, the single variable model of structural parameters has the ability to simplify the calculation process and realize the numerical calculation.关键词
