【摘要】 对单跨非径向支承部分预应力混凝土斜交曲线桥进行了理论分析,给出了其内力计算公式,并据此编制可用于实际工程设计的计算程序。为了验证理论分析与自编程序的可靠性,设计了一座单跨非径向支承部分预应力混凝土曲线梁实桥,并对实桥进行了静力试验研究。研究结果表明,该理论分析方法及计算程序可靠,可用于工程实践。更多还原

【Abstract】 An oblique curved beam with single span and non-radial bearing is analyzed, formulae are derived for calculating the internal force of the beam under 4 topical loads. Program used in the project is created based on the formulae. In order to verify the reliability of theoretical analysis and the program, the design is used for a bridge with single span and double chamber curved box beam, of which static load test is matched well with the results of the program and finite element analysis.更多还原
