摘要
盾构施工下穿既有建构筑物会不可避免的对其产生影响,基于FLAC3D数值仿真软件,分析了盾构下穿施工对不同基础形式建筑物的影响。结果表明,临近建筑物的区域其纵向沉降值会明显大于其他区域,此外,盾构下穿施工对不同建筑物的影响同时取决于其荷载大小与基础形式。最后,盾构下穿建筑物的影响区段为掘进面距离建筑物10 m左右及掘进面离开建筑物10 m左右,相应的控制举措也应在这一区段范围内施行。
Existing structures under shield construction will inevitably have an impact on them. Based on FLAC3 D numerical simulation software,this paper analyzes the impact of shield tunneling on different foundation structures. The results show that the vertical settlement value of adjacent buildings is significantly higher than that of other areas. In addition,the impact of shield underpass construction on different buildings depends on the load and foundation form. Finally,the range of influence of shield tunneling to building is about 10 m away from the building and about 10 m away from the driving surface,and corresponding control measures should also be within this range.
