摘要
文章通过八根４米跨度的预应力处合梁的静载荷试验和七组叠合式小试件抗剪强度试验，分析研究了叠会面处的应力情况、抗裂条件和提高叠合面抗剪强度的措施．成果可供设计和施工参考．
his study is dealt with the interfaces'stress condition, the crack-tdstunce condition and the method to improve the interfaces' shearing strength. Eight prestressed reinforcedconcrete composite borns were tested under static load, and seven small composite samples weretested for the shearing strength. The results may be useful for deisign and construction.
