复合地层土压盾构机施工预防地表建筑物沉降讨论复合地层土压盾构机施工预防地表建筑物沉降讨论 摘要:当前,盾构已广泛应用于城市地下隧道开挖工程中,盾构机技术已具先进水平
采纳盾构法穿越复合层层时,会造成地面建筑物的沉降,难以保证地面重要建筑物和设施的安全,同时也造成施工成本增加
本文就土压盾构机在复合层中的施工提出降低对地表建筑物影响的措施
关键字:复合地层;土压盾构机;沉降 Abstract: At present, the shield has been widely used in urban underground tunneling works, the shield machine technology with advanced level
Of Shield through the composite layers, caused by the subsidence of the ground-level structures, is difficult to guarantee the safety of ground buildings and facilities, also caused by the increase in construction costs
The earth pressure shield machine in the composite layer of construction proposed measures to reduce the impact on surface buildings
Keywords: composite stratigraphic; earth pressure shield machine; settlement 中图分类号: TQ639
