摘要
通过足尺寸的４块２跨连续叠合板和２块简支叠合板及１块简支圆孔板的试验，研究了高强刻痕钢丝预应力混凝土连续圆孔叠合板在使用荷载及极限状态下的受力性能、塑性内力重分布的特点及合理的弯矩调幅取值，进一步完善了这种叠合板的设计计算方法及有关的构造和施工措施，提出了简便易行的保证叠合面粗糙度的施工方法，为这种叠合板的工程应用提供了依据．
Through the experiments of four double spans.continuous composite slabs,two simply supported composite slabs and one simply supported hollow core slab in full size,the mechanical behavior under the serviceability loads and ultimate limit states,the characteristic of plastic internal force redistribution,and the rational moment adjust value of PC continuous hollow core composite slabs of highstrength engraved traces wires are studied.The design method and construction measure of the slabsare further perfected and a simple and convenient construction method of ensuring interface roughness is presented.These research achievements provide bases for engineering application of the slabs.
