摘　　要：对浮石混凝土与变形钢筋粘结锚固性能进行试验研究。结合56个拉拔试件的荷载-滑移（P－S）曲线的分析，提出了特征粘结-滑移（τ-s）模式，统计回归出反映各种锚固条件的特征粘结强度公式。The bond properties of deformed bars in pumice concrete are studied in this paeper. A characteristic bond-slip(l-s)relationship is derived from the force-slip(P-S) curves of 56 pull-out specimens, and the experimental formulas are established to predict the characteristic anchorage- bond strength, which accounts for each anchorage situation.
