Originální abstrakt

Local internal instability of soils subjected to seepage flow may progress and develop into the continuous seepage path, so called piping. The piping phenomena was studied by numerous authors who developed hydraulic criteria for safety assessment of global soil instability and potential dam failure. Piping in the embankment or in the foundation may be originated along the contact of soils different grain size and permeability, along the conduits in the dam body or in the weakened zones with unappropriate soil properties and stress conditions combined with considerable long-time hydraulic load. It is usually originated by local instability such as external suffosion, heave, fludisation, etc. The defect proceeds by the backward erosion, involving leaching and washing out the soil particles downstream of the dam.
