EFFECT CONFIRMATION METHOD OF FOUNDATION STRUCTURE FOR COUNTERMEASURE AGAINST EXPANSIVE GROUND
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
【課題】膨張性地盤対策用基礎構造の効果を試験的に確認することができ、信頼性の高い対策を実現するための膨張性地盤対策用基礎構造の効果確認方法を提供する。【解決手段】膨張性を示す地盤１の表面に粒状体２ａを敷設して構築される膨張性地盤対策用基礎構造Ａの効果を確認する方法であって、膨張性を示す地盤１から取得した膨張土の上に粒状体２ａを模したガラスビーズからなるガラスビーズ層を積層して試験体を製作し、試験体の側方を拘束した状態で試験体を水に浸漬させるとともに、試験体に上方から段階的に載荷圧を付加し、試験体の高さが載荷前の初期高さと同じになる載荷圧を求め、該載荷圧を膨張圧とする。【選択図】図１
