摘要
在不同的地层条件下,深基坑围护结构嵌固深度的确定原则以及计算方法不尽相同。针对软土地区围护结构嵌固深度的控制因素(抗隆起安全系数),进行各种方法的详细对比计算;结合实测资料分析,提出经济、安全、合理的建议公式,以期指导设计。
Principles and calculation methods to determine the embedded depth of a deep foundation pit retaining structures vary according to different stratigraphic conditions.Based on the comparison of various calculation methods considering different control factors(anti-heave safety factor) for the embedded depth of soft soil retaining structures and incorporating the analysis of observed data,this paper proposes a more economical,safe and reasonable calculation formula to help future design.
