Originální abstrakt

In the practical assessment of the initiation of backward erosion piping (BEP), the critical global hydraulic gradient approach is frequently used. However, the global (mean) gradient may not reflect the local conditions at the point of BEP initiation. This study applies global and local approaches to seepage and external soil erosion on the downstream slope of a 0.86 m high sandy dike. The analysis shows that even if the assessment using global hydraulic gradients provides acceptable safety in terms of internal erosion, the application of local limit state results in insufficient safety and particle instability along the seepage face.
