摘要

湿化变形是心墙坝主要后期变形之一，对坝体的应力−变形性状及初次蓄水坝体安全具有重要影响。研究堆石料湿化变形的塑性模型对完善湿化塑性理论是非常必要的。基于修正剑桥模型和利用湿化应变规律修正后的湿化剪胀方程，提出了新的湿化变形塑性模型；结合试验数据，进行了参数确定和模型的验证，发现模型计算结果与试验数据吻合良好，论证了堆石料湿化变形修正剑桥模型的准确性和合理性；同时，讨论了不同围压和不同孔隙率条件下模型参数的变化规律，给出了各模型参数在不同条件下的计算方法。研究成果完善了堆石料湿化变形的塑性理论，为后续相应研究提供重要参考和支撑。

Abstract

Wetting deformation

one of the primary types of deformation in core wall rockfill dams

significantly affects the stress-deformation behavior of the dam structure and its safety during initial impoundment. To perfect the theory of wetting plasticity

it is essential to develop a plastic model for rockfill wetting deformation. A new plastic model for wetting deformation is proposed in this paper based on the modified Cambridge model and a wetting dilatation equation derived from the wetting strain law. Based on the test data

the parameters are determined and the model is verified. The model’s calculation results are in good agreement with the test data

confirming the accuracy and rationality of the modified Cambridge model for rockfill wetting deformation proposed in this paper. Additionally

the variation rules of model parameters under different confining pressures and porosities are analyzed

and calculation methods for each parameter under varying conditions are provided. These findings enhance the plasticity theory of rockfill wetting deformation and provide valuable reference and support for future research in this area.
