直線形鋼矢板の継手強度について

Interlock Strength of Flat-type Steel Sheet Piling

中 西 輝 行(Teruyuki Nakanishi) 橋 本 隆 文 (Takafumi Hashimoto) 柴 田 克 已 (Katsumi Shibata) 武田 英俊(Hidetoshi Takeda) 三浦 啓徳(Hironori Miura) 要旨 : 直線形鋼矢板に要求される重要な特性である継手強度に及ぼす摩擦,母材特性および継手 を構成する寸法諸元の影響を,理論と実験により解析した。継手強度を高くする方法とし て,主爪および副爪のウェブ軸力分担割合に適正にし,副爪の曲げ変形を小さくする継手 の寸法諸元を選択した。その結果施工性にすぐれ,かつ継手強度700t/m が狙える継手形状 を設計することができた。 Synopsis :

Experimental and theoretical studies have been carried out on the interlock strength of flat-type sheet piling. Factors such as dimensions of interlocking part, mechanical properties of the steel and coefficient of friction have been examined to clarify their effect on the interlock strength. Also sheet piling with interlock strength expected over 700t/m and ease of driving has been designed by lowering axial load distribution to finger.
