 note = {application/pdf, 補強土構造の全体的な性状は言うに及ばず土中に埋め込んだ補強材の引き強度に対して土の含水比が重要な影響を与えることはよく知られている。その点で載荷状態にある種々のタイプの補強材の引き抜き強度について含水比の変化による効果を定量的に把握しておく必要がある。土〜補強材間の相互作用と含水比との関係を知るために,垂直応力を変化させた一連の引き抜き実験を行った。補強材として3mm間隔で径0.8mmの正方形ワイヤーメッシュを用い,引き抜き強度に関するパラメータとして土の粘着カとせん断抵抗角を測定した。また,これから得られる応力〜ひずみ関係及び体積変化特性を実際の設計,施工に利用できるように種々のチャートと図に表した。結論として,補強材の引き抜き強度と土の含水比との間に強い相関性が見られ,含水比の増加とともに粘着力,せん断抵抗角成分が減少していく傾向が明らかとなった。, It is well known that the water content of soil has a significant effect on the pullout strength of reinforcement embedded in soil, as well as on the overall performance of reinforced soil structures. Since the substantial amount of water in soil varies throughout the year, it is of prime importance to investigate the effect of water content on pullout strength of reinforcement when subjected to loading with various types of reinforcement. A series of pullout tests under variable normal stresses have been carried out in order to find out the effect of water content on soil reinforcement interactions under pullout test in reinforced soil structures. In this paper, an investigation of the pullout strength of reinforcement parameters such as cohesion and internal friction under laboratory pullout tests for woven square wire mesh with 3 mm openings and 0.8 mm wire diameter is presented. Stress-displacement relationships and volumetric changes under laboratory pullout tests are given in various charts and diagrams as a ready reference to aid in practical design and constructions. It appears from the results of the pullout tests performed that there exists a relationship between the pullout strength of reinforcement and water content of soil. It is concluded that the pullout strength of reinforcement such as frictional resistance and cohesion both are decreased with the increase in water content of the soil., 原著論文 / Original Article},
