 note = {近年の地震による水道管被害は, ダクタイル鋳鉄管の継手抜け出しによる事例が多く報告されている. ダクタイル鋳鉄管は, 抜け出し防止機能を有する耐震継手, 有しない非耐震継手とに大きく分類され, 耐震継手の被害報告は無い. 非耐震継手は, 主に製造年代と口径により継手形式が異なることから, 被害率と継手形式とは関係があるものと推測される. 　本稿は, ダクタイル鋳鉄管の継手別被害から耐震適合性の新たな判断指標を提案することを目的とした研究の一環として, 継手別の抜け出し抵抗力の違いを実験により求め, 既往の研究との対比を行った. その結果, ダクタイル鋳鉄管の抜け出し抵抗力は継手によって差があることを明らかにした. In recent year, most of water pipe damages caused by earthquakes have been reported by pull out at joint. Ductile iron pipe are classified as mechanical type for earthquake-proof or non-earthquake-proof joint and slip-on type for non-e-proof joint. The earthquake proof joint never been damaged in the past earthquakes but the damage for another types of joint occurred frequently. Since the type of joint depends on the manufaction age and pipe diameter. Therefore, it could be estimated the relation between the damage rate and joint type. This paper focused on this issue. The resistance force against pull out at joint was clarified by the experiments and the results are discussed. Finally the earthquake adaptability for the different joint types is proposed.},
