Document Type and Number:
Japanese Patent JP7240667
Kind Code:
B2
Abstract:
To resolve problems that prior arts have and thus provide an earth structure and a method that can prevent scouring of the front, piping that occurs at the rear, and seepage destruction of a levee body, and that can prevent sliding of the inside of the levee body and sinkage of the levee body due to liquefaction when an earthquake occurs.SOLUTION: A reinforced earth structure of this invention comprises a front slope surface and a rear slope surface, and further includes: a "body"; an "impermeable improvement body" that has permeability lower than that of the body; and a "permeable improvement body" that has permeability higher than that of the body. Note that the main material of the impermeable improvement body is a cement-based material, and the impermeable improvement body is formed on a part of the front slope surface including slope toes. On the other hand, the main material of the permeable improvement body is a cement-based material, and the permeable improvement body is formed on a part of the rear slope surface including slope toes.SELECTED DRAWING: Figure 2
