Rainfall Erosion Damage of Residual Soil Slope in Intermittently Frozen Area Based on Discrete Element Method
نویسندگان
چکیده
This study developed a discrete element simulation model based on the 2D particle flow code (PFC ), of which mesoscopic parameters were calibrated by indoor experiments, to investigate rainfall erosion damage residual soil slope in intermittently frozen area. It is be noted that runoff scouring action was simulated according equivalent method, particles given initial velocity, and water absorption considered increasing unit weight. The results indicated only caused superficial with main region at foot, regardless FT effect. A splitting phenomenon observed lower part steeper under Moreover, effect, gentler tended incur spalling rather than phenomenon, where slid along structural plane strong anti-scouring ability. Besides, maintained higher stability shorter time. Finally, velocity increased large extent.

Rock Slope Stability Analysis Using Discrete Element Method
Rock slope stability depends very much on the strength features of the rock and the geometrical and strength characteristics of the discontinuities (e.g., roughness, wall strength and persistence). Since a rock mass is not a continuum, its behavior is dominated by such discontinuities as faults, joints and bedding planes. Also, Rock slope instability is a major hazard for human activities and o...

Hysteretic sediment fluxes in rainfall-driven soil erosion
Hysteresis patterns of different sediment particle sizes were studied via a detailed laboratory study and modelling. Seven continuous rainfall events with stepwisevarying rainfall intensities (15, 30, 45, 60, 45, 30 and 15 mmh-1, each 20 min duration) were conducted using a 5-m× 2-m erosion flume. Flow rates and sediment concentration data were measured using flume discharge samples, and interp...
