摘　　要：本文通过咬合试验和内贴片试验,进一步研究砌块专用砂浆和钢筋的粘结机理,分析了内裂缝的发展过程和粘结应力的分布,建立了粘结应力的分布函数,并通过咬合试验和内贴片试验的对比,进一步验证了咬合试件试验,除了受力和变形状态与内贴片试验不完全一样外,粘结与滑移的特性是类似的。Through the of lock seam test and internal veneering test, a further nvestigation of bond mechanrsm between mortar used in concrete block masonry and bar was between carried out. Inner cracking course and bon stress drstribution was analyzed;Drstrrbution function of bond stress was established. Two tests mentioned above were testrfied similar in the features of ond and slrp except straining and transfiguration on samples.
