摘　　要：锚锭板是一种承受土体被动抗力的结构单元,常用于支挡结构、板桩锚固和管线转弯处的设计和施工。本文采用一种描述锚锭板极限拉拔荷载的统一表达式,根据砂土中锚锭板试验结果的统计分析、粘土中锚锭板有限单元上下限解结果和试验资料的整理,给出了锚锭板极限拉拔荷载统一表达式中相应参数的取值范围。该统一表达式可直接应用于锚锭板极限拉拔荷载的估算,也可进一步应用于其它地埋结构(如侧向受荷桩)的弹塑性分析。Anchor plates are buried structures for resisting passive earth pressure, widely used for design and construction of retaining wall structures, sheet pile bulkheads and pipeline bends. In this paper, a unified expression was presented to describe the ultimate pullout capacity of anchor plates. Using records of experimental data from literatures, the parameters in the unified expression for anchor plates in sand or clay were statically analyzed. For the anchor plates in clay, the parameters were also derived in details from the results of finite element limit analysis of buried anchor plates herein. The expression could be directly used to evaluate the ultimate pullout capacity of anchor plates and further applied to the elastic-plastic analysis of other buried structures, such as laterally loaded piles.
