摘要
阐述了波形钢腹板PC箱梁桥的结构特点,概括了国内外在波形钢腹板箱梁偏载作用下力学性能研究、箱梁弯曲承载能力研究、钢腹板与顶底板混凝土连接形式研究、波形钢腹板稳定性研究及体外预应力筋的参数分析等方面的研究现状.给出了部分国内外此类桥梁一览表,归纳了波形钢腹板混凝土组合桥梁的最新桥型发展趋势,最后指出了波形钢腹板-混凝土组合桥梁需进一步深入研究的方向.
The structural characters of PC box beam bridge with corrugated shaped abdominal scute are introduced. The reports of both domestic and oversea study is summarized including the mechanics performance with the eccentricity load, bending bearing capability, connection type between the corrugated steel abdominal scute and concrete, stability analysis andparameter analysis of external prestressing bar. The schedule of such composite bridges is subsequently given. The latest development trends of this type bridges are also concluded.Finally, the farther research aspects are indicated.
