摘　　要：杭州大江东基础设施项目河景路K4+178~K4+300段道路路基回填高度较高,且位于地铁8号线盾构区间保护范围正上方,为实现保护区内盾构不受影响的同时还兼顾质量施工。决定对受影响范围进行轻质气泡混凝土填筑施工,有效降低地铁上方附加荷载,减小对地铁结构的扰动,保证地铁运维安全,节约施工成本,有效解决保护区范围路基施工的难题。The roadbed backfilling height of the K4+178~K4+300 section of Hejing Road in Hangzhou Dajiangdong Infrastructure Project is relatively high,and it is located directly above the protection range of the shield tunneling section of Metro Line 8.In order to ensure that the shield tunneling in the protected area is not affected while also considering the quality of construction,it has been decided to carry out lightweight bubble concrete filling construction in the affected area.It effectively reduces the additional load above the subway,reduces disturbance to the subway structure,ensures the safety of subway operation and maintenance,saves construction costs,and effectively solves the problem of roadbed construction within the protected area.
