EXAMINATION METHOD OF CONSOLIDATION YIELD STRESS
PROBLEM TO BE SOLVED: To provide an examination method of consolidation yield stress capable of determining the consolidation yield stress only by a hole inner loading test of using a hole bored in the ground, without executing a boring examination, a sounding test and an indoor soil test.SOLUTION: An examination method is composed of a hole drilling process of forming an examination hole in the substantially vertical direction in the examination ground, a hole inner loading test process of measuring a displacement amount of the ground in respective pressures, by loading a cargo stepwise to a wall surface of the examination hole by expanding an expansion body, by inserting the expansion body into the examination hole formed in the hole drilling process or installing the expansion body by self-boring, a final displacement amount analytical process of analyzing the final displacement amount from the displacement mount measured by the hole inner loading test process and a consolidation yield stress analytical process of analyzing consolidation yield stress from the final displacement amount and loading pressure analyzed by the final displacement amount analytical process.SELECTED DRAWING: Figure 1
【課題】 本発明はボーリング調査やサウンディング試験、室内土質試験等を行うことなく、地盤にあけた孔を利用した孔内載荷試験のみで圧密降伏応力を求めることができる圧密降伏応力の調査方法を提供することを目的としている。【解決手段】 調査地盤に調査用孔を略垂直方向に形成する削孔工程と、該削孔工程で形成した調査用孔内に膨張体を挿入し、あるいはセルフボーリングで膨張体を設置し、該膨張体を膨張させ調査用孔の壁面に対して段階載荷し、各圧力における地盤の変位量を測定する孔内載荷試験工程と、該孔内載荷試験工程で測定した変位量から最終変位量を解析する最終変位量解析工程と、該最終変位量解析工程より解析された最終変位量と載荷圧力から圧密降伏応力を解析する圧密降伏応力解析工程とで成ることを特徴とする。【選択図】 図１
