锚拉桩基础锚定板挡墙在临近已建挡墙填方工程中的应用

本文结合福建省某高路堤边坡锚定板挡墙工程，介绍锚拉桩基础锚定板挡墙在临近已建挡墙之上填方加高边坡的应用和设计方法。为避免新填筑边坡填土荷载对下方临近已建支挡结构的影响，锚定板挡墙可采用锚拉桩基础卸除附加土压力。实践证明这是一种技术可行且经济合理的方法。

Application of anchor breast wall with anchorage tensile pile foundation in filling project near the existing retain wall

Combined with a high bank slope anchor breast wall project,the application and design method of anchor breast wall used in heightening slope filling near existing retain wall is introduced.The anchorage tensile pile foundation is used to avoid the influence of load on existing structure by new filled soil,which had proved to be a feasible and economic method.
