| Abstract: | Taking the inverted-triangle area of Yingzhou Bridge as the object of study,temperature monitoring scheme is determined,and pouring temperature field of box girder concrete is analyzed by applying finite element analysis program.The distributing rules of temperature field and stress field in the whole construction process are obtained,thus having important guidance meaning on prior pouring forecast and pouring process control of inverted-triangle area. |
