摘要
结合亳州市307省道与105国道连接线下穿京九铁路立交桥工程实例,介绍高水位、流砂地区顶进框架桥施工防范流砂的关键技术措施,重点介绍降水、基坑支护和开挖、铁路路基加固及封水处理等技术措施。
Combined with the engineering practice of Bozhou City Provincial Rd 307 and State Road 105 connecting line crossing under the Beijing-Kowloon railway overpass project,the paper introduces the key technical measures of the jacking frame bridge to prevent quicksand in higher water level of quicksand area with focus on precipitation,foundation pit excavation,and railway roadbed reinforcement and water sealing technology measures.
