| 摘 要： | 连续刚构桥作为一种经济实用的桥型，在西部地区得到广泛应用。然而，随着使用年限的增加，跨中下挠成为一种不容忽视的典型病害，严重影响桥梁的正常使用。通过大型有限元程序ANSYS的高级开发技术UPFs和FORTRAN77语言，开发适合混凝土徐变规律的用户程序，实现对桥梁病害的模拟和分析，得出预防此类病害的具体措施。

| Abstract: | Being economical and applicable,continuous rigid frame bridge has found wide application in western China.However,with time,the mid-span deflection became a marked disease,and even influenced the common use of the bridge.A user creep program is compiled with ANSYS UPFs and FORTRAN77 for the simulation and analysis to this disease.Some preventive measure is put out to avoid the disease of mid-span deflection. |
