| 摘 要： | 基于按龄期调整的有效模量法结合有限单元逐步分析法，对ANSYS程序进行了计算混凝土桥梁徐变的二次开发。详细介绍了按龄期调整的有效模量法的具体计算步骤，并将计算结果与理论值进行比较，结果吻合的很好，且符合有砟轨道预应力混凝土箱梁的设计要求；验证了程序的正确性同时得出一些有益的结论：徐变对混凝土桥梁的影响不容忽视，必须予以重视。

| Abstract: | Based on the age-adjusted effective modulus method and the finite element gradual analysis method,are-development is made of the ANSYS programm for the creep calculation of concrete bridges.The specific calculating steps of the age-adjusted effective modulus mothod are also introduced in the paper,with the calculated result compared with the theoretical values,through which it is found that the two results are in full agreement,and also in accordance with the design requirements for the dreggy track pre-str... |
