Resumo:  6個の圧力センサを利用して耕盤での土中応力状態を測定可能な土中応力測定器 (以下測定器) を開発した。測定器をタイヤ進行方向のタイヤ中心部およびタイヤ側端のラグ直下ならびにタイヤ側端のアンダートレッド直下の3ヶ所に土壌表面から深さ25cmの耕盤上に埋設し, タイヤを走行させて土中応力を測定した。得られたデータから応力状態を算出し, 主応力を求めた。次に, 測定器の埋設位置の違いによる最大主応力を検討した。その結果, タイヤ中心部ラグ直下における最大主応力が, タイヤ側端部でのそれの2倍以上になっていることが分かった。 A transducer was developed to determine the stress state in the soil on a hard pan. Principal stresses, octahedral normal and shearing stresses can be calculated from the data measured with six pressure cells on the transducer in the six predetermined directions. The transducer was buried in three locations in the soil at 25cm depth : under the lug at the centerline and the edge of the tire and under the undertread at the edge of the tire. The effect of changes in the locations of buried transducer on soil stresses indicated that the maximum major principal stress under the lug at the centerline of the tire in was more than twice as those in other locations.
