摘要

置于外界环境中的桥梁受到外界影响而产生的温度效应通常难以计算．结合美景大桥的监控工作，采用“时间-温度-变形-应力”同步的测试手段，对该桥箱梁的温度场及其效应进行了现场实测；运用有限元分析软件MIDAS CIVIL分析箱梁桥的温度场，验证了MIDAS CIVIL温度场分析结果的正确性．对比分析了理论计算值与实测值间的误差，更好地把握温度效应影响的大小，为桥梁施工监控中的主梁立模标高实时修正提供依据，并为预应力连续箱梁桥选择合适的合拢温度．

Abstract

Temperature efects that arise in bridges exposed to the environmental variables are not easily estimated．Based on the Mei Jing Bridge supervision work，the temperature field and the strain field of the box beam are measured on site by means of“Time-Temperature-Deformation-Stress”．It simulated the temperature field with software MIDAS CIVIL and vertified the accuracy of results．By measuring and analysing the difenrences between the theoretical value and the actual values，the temperature effects are better controlled．It provides the basis for real-time correction of elevation of the main beam in Construction Monitoring，and selects the appropriate temperature for the PC continuous box girder bridge closure．
