摘要:
针对大跨混凝土刚构桥成桥线形对桥梁受力影响很大这一问题,介绍了施工过程中影响桥梁线形的主要结构因素及其概率分布.提出了基于响应面法进行大跨混凝土刚构桥参数识别和标高控制动态可靠度评估方法,该评估方法包括试验设计、有限元分析、响应面函数拟合、参数识别和标高控制动态可靠度评估.以镇大公路运河大桥为例,利用施工监测数据进行结构施工过程中的参数识别,对施工过程中的标高控制动态可靠度进行评估.通过标高控制动态可靠度来确定各关键截面的允许施工误差,将参数识别和标高控制动态可靠度相结合实现施工过程中的线形控制.
Abstract:
The finial linear form of long-span prestressed concrete rigid frame bridges affects its stress state. The factors affecting the finial line are introduced, and their probability distributions are also introduced. The method of dynamic reliability evaluation and parameter identification for large-span concrete bridge is put forward based on the response surface during construction monitoring. The method includes experimental design, finite element analysis, fitting the response surface function and evaluating the dynamic reliability. Taking the practical engineering of Zhenda highway canal bridge for example, the parameters were identified and the dynamic reliability during construction process were evaluated, and the allowed construction error of key section was determined using dynamic reliability data. The ideal final linear form was achieved by combing structure parameter identification and dynamic reliability evaluation.
