摘要
隔离桩作为一种有效的保护措施已经在地铁深基坑工程中得到比较广泛的应用,但是目前对其作用原理仍缺乏系统的理论研究和规律性的认识。以上海某地铁基坑邻近建筑物保护实际工程为背景,建立有限元模型,分析了隔离桩长度﹑位置及桩体刚度对邻近建筑物差异沉降的影响,并将数值分析结果与实测值比较,得到了有益的结论,可供类似工程参考。
Protection for buildings close to metro deep excavation has became more and more important with the development of urban rail transit,in which isolation piles are widely used in practical project as an effective method,but the research on the protection mechanism is far from being systematic.In this paper,a practical project of isolation piles is used in building protection is analyzed comprehensively with FEM software,the influence of pile length,pile rigidity and pile location on settlement of buildings around metro deep excavation is studied,so as to provide some refrences for similar projects.
