摘要
北京地铁光华路车站采用单跨三洞分离岛式结构,车站中洞与侧洞最小间距仅4.5m。为改善车站结构各硐室的整体受力性能,确保群洞施工安全,需要对洞间土体进行注浆加固。根据不同地层条件,提出土体注浆加固的机理和方法,并作了效果评价。
Guanghua Road station of Beijing metro adopts single-span-three-hole separated island platform structure,the shortest distance between the center drift in station and the side drifts is only 4.5m.In order to improve the integral forced performance of a tunnel,and to guarantee the construction safety,need to grout to the soil-body among the tunnels.According to varied formations,the mechanism,method,effectiveness evaluation on soil-body reinforcement is proposed.
