Formation of layered fracture and outburst by percolation

Formation mechanism of layered fracture and outburst in soils is investigated. It is shown that once the pore pressure is high enough to cause the over-cap failure, layered fracture or outburst occurs in liquefied or gasified sediments. The formation conditions are related to the strength of sedimen...

Description
Summary:Formation mechanism of layered fracture and outburst in soils is investigated. It is shown that once the pore pressure is high enough to cause the over-cap failure, layered fracture or outburst occurs in liquefied or gasified sediments. The formation conditions are related to the strength of sediments and the boundary friction.
