摘要
对贵阳南环线花溪一号桥拱座大体积混凝土温度控制措施进行描述,对结构进行了有限元模拟分析,介绍了通过对混凝土温度场的控制来控制混凝土应力场的方法,达到了温度应力的预期控制效果。
Combined with practical work of Huaxi No. 1 arched bridge in Guiyang temperature control measures of mars of abutment is described. In addition, finite element simulation analysis is carried out for structure. The control method of stress field of concrete by tempera-ture field is introduced in order to realize pre-control of temperature stress of mars concrete.
