| Abstract: | With the Luotianle Continuous Rigid Frame Bridge construction as the case,the article applied the finite element model to conduct the numerical simulation analysis on the changes of temperature field in the process of 0# Block concrete placement construction.The result showed that the internal maximum temperature and the maximum calculation value of temperature difference between inside and outside of 0# Block concrete matched well with the actual measured value. |
