Slope Stability Analysis of Rockfill Embankments Considering Stress-Dependent Spatial Variability in Friction Angle of Granular Materials

Applied Sciences
Slope stability is a major safety concern of rockfill embankments. Since rockfills are incohesive materials, only friction angle is considered as a shear strength parameter in the slope stability analysis of rockfill embankments.

Measurement method of time-varying degradation characteristics of rockfill particle strength and its preliminary application

Yantu gongcheng xuebao
It is typically assumed that the strength of individual particles deteriorates with time when using the discrete element method (DEM) to model the creep behaviour of rockfill materials under loading.

Calculation of rockfill deformation based on the generalized plastic framework

Shuili Shuiyun Gongcheng Xuebao
Rockfill is the primary load-bearing material in earth-rock dams, crucial for withstanding water pressure. Developing a constitutive model that accurately describes its mechanical properties is essential for predicting the stress and deformation in high ...
