膨張性地盤対策用基礎構造の効果確認方法
Document Type and Number:
Japanese Patent JP6873823
Kind Code:
B2
Abstract:
To provide an effect confirmation method of a foundation structure for countermeasure against an expansive ground for realizing a countermeasure with high reliability, which can experimentally confirm an effect of a foundation structure for countermeasure against an expansive ground.SOLUTION: An effect confirmation method of a foundation structure A for countermeasure against an expansive ground which is constructed by laying granular materials 2a on a surface of an expansive ground 1 comprises: making a test body by laminating a glass bead layer constituted of glass beads simulating granular materials 2a on an expansive soil obtained from the expansive ground 1; immersing the teat body into water in a state where a lateral side of the test body is restricted; gradually applying load pressure onto the test body from above; and obtaining a load pressure at a time when a height of the test body becomes same as an initial height before loading. The obtained load pressure is considered to be an expansive pressure.SELECTED DRAWING: Figure 1
