摘要: 锚拉桩支护体系中,桩的嵌固深度确定至今仍是一个探讨性的问题,尽管目前有许多可供选用的方法对嵌固深度进行计算,但无论何种方法,其合理性仍未在工程界达成共识,因而也未正式列入国家或行业的相关规范中。通过工程实例,对锚拉桩嵌固深度计算基本假定、计算模型的分析确定、具体计算过程等方面进行了详细分析和论述,以供同行在工程设计时进行对比参考。

Abstract: In the excavation supporting system involving with tensional anchored piles, the pile bounding length determination is still a research topic. There is no general consensus in the engineering practice although several bounding length estimation methods are available. No national or industrial design code adopts the bounding length estimation method. This paper proposes a new simplified method of estimating the bound length of tensional anchored piles. The predicted results have been used in a project.
