摘要
依托天津体育中心地铁车站深基坑施工,研究了软土地层中深基坑土方开挖对附近既有建筑、基坑围护结构及基坑外部土体的影响,利用数值模拟和现场实测相结合的方法,发现距离基坑33m之外的既有建筑沉降量或隆起量非常小,得到了地下连续墙水位位移在高度上的分布规律,地下连续墙变形在基坑开挖后的25周后趋于稳定。
Based on the deep foundation excavation construction of Tianjin Sports Center subway station, the effect on existing buildings, foundation excavation support structures and soil outside of excavation was analyzed, and by the means of numerical simulation and field measurement, the deformation rule of diaphragm wall in vertical direction was gained, and its horizontal displacement trends to be stable after 25 weeks. The upheaval or settlement of existing buildings is tiny.
