不同冷却水管布置对温度及温度应力影响分析
nalysis of Influence on the temperature and thermal stress made by different arrangement of water-cooling pipes
水管冷却是防止大体积水工混凝土裂缝的主要措施，本文结合某拱坝工程的实际情况，对河床坝段采用有限单元法，应用平面有限元程序，对坝段整体施工期和运行期温度场，温度徐变应力场进行仿真计算，考虑不同的水管冷却对温度和温度徐变应力的作用及影响，为拱坝河床坝段的温控提供参考依据。
Pipe cooling is a major measure of prevention crack of mass -hydraulic concrete, Based on fininte element technique and by using plan finite element program,In this paper, different arrangement of water-cooling pipes is considered to carry out the simulation analysis of the temperature and thermal stress field of the arch dam during construction and operation period in according to the practical situation of the project, which aim to offer reliable basis for taking correpending temperature contorl mesures of arch dam bed segment during construction period.
