The Duncan-Zhang model is not able to reflect the influence of the mid-major stress on the strength and deformation of the rockfill body in the finite element calculations of the panel rockfill dam. The Duncan-Zhang E-B model and its optimization model for the panel rockfill dam has been developed by the secondary development of ANSYS based APDL language. The Duncan-Zhang E-B model and its optimization model were used to calculate the three-dimensional finite element static force of a panel rockfill dam in Yunnan Province. The results show that the settlement of the dam body was reduced, the horizontal displacement was reduced, and the stress change was small. The strain results obtained from the optimization model are closer to the actual data. The optimizaion Duncan-Zhang E-B model considering the medium principal stress can better reflect the stress-deformation characteristics of the panel rockfill dam.

针对邓肯-张模型在面板堆石坝有限元计算中不能反映中主应力对堆石体强度和变形的影响,利用APDL语言对ANSYS进行二次开发,开发出邓肯-张E-B模型及其优化模型的计算程序模块。分别采用邓肯-张E-B原始模型及其优化模型对云南省某面板堆石坝进行三维有限元静力计算,结果显示由优化模型计算得到的坝体沉降减小、水平位移减小,而应力变化较小;优化模型的计算结果更接近实际值。可见考虑了中主应力的优化邓肯-张E-B模型可更好地反映面板堆石坝的应力变形特性。

针对邓肯-张模型在面板堆石坝有限元计算中不能反映中主应力对堆石体强度和变形的影响,利用APDL语言对ANSYS进行二次开发,开发出邓肯-张E-B模型及其优化模型的计算程序模块。分别采用邓肯-张E-B原始模型及其优化模型对云南省某面板堆石坝进行三维有限元静力计算,结果显示由优化模型计算得到的坝体沉降减小、水平位移减小,而应力变化较小;优化模型的计算结果更接近实际值。可见考虑了中主应力的优化邓肯-张E-B模型可更好地反映面板堆石坝的应力变形特性。

The Duncan-Zhang model is not able to reflect the influence of the mid-major stress on the strength and deformation of the rockfill body in the finite element calculations of the panel rockfill dam. The Duncan-Zhang E-B model and its optimization model for the panel rockfill dam has been developed by the secondary development of ANSYS based APDL language. The Duncan-Zhang E-B model and its optimization model were used to calculate the three-dimensional finite element static force of a panel rockfill dam in Yunnan Province. The results show that the settlement of the dam body was reduced, the horizontal displacement was reduced, and the stress change was small. The strain results obtained from the optimization model are closer to the actual data. The optimizaion Duncan-Zhang E-B model considering the medium principal stress can better reflect the stress-deformation characteristics of the panel rockfill dam.
