摘要
综合考虑了影响桥梁结构温度场变化的各种环境因素和施工监控的实际情况 ,把复杂的边界条件简化成两类简单的温度荷载 ,用有限元法解决了温度场的短期预测问题。最后以荆州长江大桥主桥 5 0 0m跨标准梁段温度场预测作为实例 ,验证了该方法的可行性。
Considering all the factors which affect the temperature field of concrete cable-stayed bridge and the actual state of construction control, the authors simplify the complicated border conditions to two simple temperature loads. The method of finite element has been used to solve the short term forecast of temperature field. Finally, numerical results are presented to demonstrate the accuracy and effectiveness of this method.
