钢筋混凝土桁架拱桥承载能力的检测与评估

为了研究钢筋混凝土桁架拱桥承载能力的检测与评估方法,以一座跨越黄河的钢筋混凝土桁架拱桥为工程背景,通过查阅工程资料、现场调查、建模计算、荷载试验的方法对该桥的承载能力做出了综合性的评估。研究结果表明:钢筋混凝土桁架拱桥的承载能力评估是一项复杂的、综合性的评估,仅凭某种单一的检测手段无法对其作出科学客观的评价,应综合考虑其工程背景、区域规划、理论模型及实际工作状态,才能对其作出科学客观的评价与建议,这样既能保证桥梁的运营安全又不会造成资源的浪费。

Detection and Evaluation of Bearing Capacity of Reinforced Concrete Truss Arch Bridge

In order to study the detection and evaluation methods of the bearing capacity of reinforced concrete truss arch bridge,taking a reinforced concrete truss arch bridge across the Yellow River as the engineering background,the bearing capacity of the bridge is comprehensively evaluated by consulting engineering data,field investigation,modeling calculation and load test.The research results show that the bearing capacity evaluation of reinforced concrete truss arch bridge is a complex and comprehensive evaluation,which cannot be evaluated scientifically and objectively only by a single detection method.Only by considering the engineering background,regional planning,theoretical model and actual working state,can the scientific and objective evaluation and suggestions be made,which can not only ensure the safe operation of the bridge,but also not cause the waste of resources.
