摘要
目前国内许多城市通过修建桥梁来方便市民出行以及缓解城市交通压力。因此,在城市修建地铁车站基坑时可能会遇到近接桥梁桩基的情况,而基坑的施工必然会对其造成影响甚至破坏,这便给城市基坑施工增加了难度。本文通过数值计算与调研方法确定了基坑施工对近接桥梁桩基的影响分区,将影响分区分为强影响区、弱影响区以及无影响区三类,并针对各影响分区提出了相应的控制措施。在基坑施工过程中,可根据桥梁桩基所处分区决定应对其采取何种措施,以保障基坑施工过程中近接桥梁桩基的安全。
Today,many cities built bridges to facilitate public travel condition and alleviate the urban traffic pressure.As a result,building a foundation pit in prosperous area of the city should be close to existing bridge piles,which should be affected by the construction of foundation pit,and how to protect adjacent existing bridge piles becomes a big problem in the construction of foundation pit in the city.Through numerical calculation and investigation,this article put forward the influence zones of foundation pit excavation adjacent to bridge piles,and divided the influence zones into strong influence zones,weak influence zones and no influence zones,and gave measures according to the influence zones.During the construction of foundation pit,it was useful to take corresponding measures depending on which influence zone that the bridge piles in.
