| 摘 要： | 该文介绍了大跨径连续箱梁施工过程中考虑温度影响的线形控制方法。文中给出了采用“固定时间观测法”和“相对标高放样法”进行线形控制的计算公式，在广州市绕城高速公路西二环巴江河大桥悬臂施工中采用“相对标高放样法”控制大线形．理论计算值和实测值基本吻合。

| Abstract: | The article introduces the alignment control method considering the temperature influence in the course of large-span continuous box beam construction. The article gives the calculation formula using "fixed time observing process" and "relative elevation lofting process" to carry out the alignment control. The "relative elevation lofting process" is used in the cantilever construction of Bajiang River Bridge in West No.2 Ring of the expressway surrounding Guangzhou City to control the large alignment. The t... |
