基于三轴试验的邓肯张模型参数的确定方法

The Method of Determining Triaxial Test-based Duncan Chang Model Parameters

由于邓肯—张模型反映了土体变形的主要规律并且其各项参数易于从常规三轴试验求得而在工程实践中被广泛应用,因此通过对邓肯—张双曲线型模型的推导,获取材料参数之间的关系,通过三轴试验数据的分析,确定邓肯—张双曲线模型的参数。

Since Duncan - Chang Model reflects the principal law of earth mass deformation, and its various parameters could be acquired from the conventional triaxial test and widely used in construction of hydro projects, it is therefore to obtain the relationship between material parameters by derivation of Duncan- Chang hyperbolic curve type model and then to determine the parameters of Duncan - Chang hyperbolic curve model through analysis of triaxial test data.
