摘要
在建基坑工程的相邻水环境变化直接影响到基坑围护结构的安全。通过有限元数值模拟计算,针对相邻排水河道水位的变化,分析了高水位条件下的基坑渗流场特性、围护结构系统的整体工作性状,从围护结构变形、锚索工作拉力等角度评价了基坑的安全状态,为类似基坑安全评估提供了实用的借鉴方法。
Changes of water environment adjacent to under construction of foundation pit directly influence the safety of exteri- or-protected structure. Based on the finite element numerical simulation method, the character of seepage field and the whole working state of structural support system are analyzed in the condition of adjacent high stage of drainage watercourse. In addition, the safe statue of the pit is evaluated based on the deformation of structural support and the anchor tension. This paper could provide reference and consult for the design and construction of similar deep foundation pit.
