Abstract: Taking Shuikou bridge as an example,according to the measured ambient temperature and pouring temperature and the transient heat conduction equation,simulation analysis of block number zero’s temperature in depositing period was conducted by using finite element analysis software ANSYS.After comparing the simulation results and the measured data, it shows good result.Calculation shows that,concrete pouring temperature has linear effect on temperature field,hydration heat coefficient influence of temperature peak value and occurrence time; outside air temperature could exert great effect on temperature field.

Key words: continuous rigid frame bridge, zero block, hydration heat, finite element method, temperature field

摘要: 以水口大桥为例,根据实测外界环境温度、浇筑初始温度等条件,按照瞬态热传导方程,运用有限元分析软件 ANSYS 对该桥0 号块水化热温度场进行分析,并将仿真结果与实测数据比较,两者吻合较好。结果表明:混凝土浇 筑时的初始温度与瞬态温度场呈线性关系,水化热系数同时影响温度峰值及其出现时间,外界大气温度对后期温度 场影响较大。
