建立了粘结应力沿锚固长度的分布模式。
The distribution model of bond stress over the splice length is developed.
研究表明：活性粉末混凝土与钢筋的极限粘结应力随着钢筋直径的增加而下降，钢筋直径相同时随着锚固长度的增加而降低。
Results indicate that the ultimate bond stress between bars and RPC decreases with the increase of bar diameter or with anchorage length when bar diameter is the same.
并对测试结果进行了拟合，得出了锚固段粘结应力分布的拟合方程。
