Abstract

The invention discloses a large-scale dike piping dangerous case evolution mechanism physical simulation device, and relates to the technical field of dike piping dangerous case evolution mechanism physical simulation devices. According to the large-scale dike piping dangerous case evolution mechanism physical simulation device, the impermeability of a sand layer pressure water head and a covering layer is monitored according to a seepage field monitoring system; under the condition that the upstream area of the covering layer with the piping opening which not expanded and the upstream area of the covering layer with the piping opening which not expanded can resist the jacking effect of a confined water head and cannot be damaged, the covering layer is exposed by disassembling the cover plate on the detachable and replaceable cover plate system, conditions are provided for the piping opening which is not to be restrained when the piping opening is expanded to the upstream, and a real dike piping danger expansion process is simulated.

Description

technical field

[0001] The invention relates to the technical field of a physical simulation device for the evolution mechanism of embankment piping danger, in particular to a physical simulation device for the evolution mechanism of large-scale embankment piping danger. Background technique

[0002] Piping danger is one of the most common dangers in embankments in our country, which seriously affects the safe operation of embankments and has caused great losses to the lives and property of our people over the years. Piping refers to the phenomenon that under the action of seepage, the fine particles in the non-cohesive soil move or are carried out through the gaps of the coarse particle skeleton, resulting in the formation of channels in the soil layer and the phenomenon of concentrated water gushing. Indoor physical model test is one of the main methods to study the mechanism of piping hazards, but the physical models currently used have shortcomings: (1) the size of the m...
