摘要
重庆石板坡复线桥在连续刚构桥中首次实现330 m的跨径,钢-混凝土接头的采用,在世界同类型桥梁设计中也属首次。由于设计的安全合理至关重要,所以通过理论与试验分析来检验钢-混凝土接头结构设计的合理性,验证设计计算理论和方法的正确性。该试验研究成果为钢-混凝土接头在同类桥型中推广使用积累了试验资料和科学依据。
For the first time in continuous rigid frame bridges, new Chongqing Shibanpo bridge has adopted 330m span, and the use of steel - concrete connector is also a first in similar bridge designs in the world. Therefore the safety and rationality in design is critical. Through theoretical and experimental analysis, this paper testifies the design of rationality of steel - concrete connector structure, and verifies the correctness of design/computing theories and methods. In the same time, it accumulates test data and scientific basis for promoting application of steel - concrete connector in similar bridges, the test and research results will provide basis for both design and construction.
