摘要
结合广深四线下李朗DK3+6191-18 m框架施工实例,介绍了大跨度斜交框架下穿既有线施工方法的比选、支点转换法顶进的施工技术要点,从而为类似工程施工积累经验。
By combining with the DK3 + 619 1-18 m structure construction in Xialilang along No. 4 railway Guangzhou-Shenzhen, the paper introduces the comparison and selection of the construction method the existing line construction of the large-span skew frame structure and the technical points for the pivot conversion method, so as to accumulate experience for similar constructions.
