摘  要:
选择混凝土密度、弹性模量、预应力误差、混凝土收缩徐变及温度变化等,分析了各参数对连续刚构桥梁线形和内力的影响程度。根据计算结果,确定了施工监控的主要参数,并提出了施工过程中进行预应力摩阻试验和避免温差影响的监控意见。相关结论可为同类桥梁的设计和施工提供参考。

摘  要:
Influences of various parameters,such as concrete density,elastic modulus,the error of prestressing force,shrinkage and creep of concrete,and temperature change,on the linear and internal forces of the continuous rigid frame bridge were analyzed.The main parameters for construction control were determined.It suggests that the inherent stress friction test should be conducted to avoid the temperature influence in the construction process.Relevant conclusions can be used as references for the design and construction of the similar bridges.
