锚定板挡土结构

锚定板挡土结构 English Version

摘要: 锚定板挡土结构是一种新型的挡土结构,由预制的钢筋混凝土墙面、钢拉杆和埋在填土中的锚定板组成。这种结构依靠填土与结构的相互作用力而维持其自身的稳定。与重力式挡土墙相比,锚定板结构轻便并较有柔性。它特别适用于地基承载力不大的地区。本文概述锚定板结构内力平衡和整体稳定的计算方法和原理,并介绍一些已建成的锚定板结构的长期观测结果。

Abstract: The anchor slab structure is a type of retaining wall which consists of prefabricated face panels, tie-bars and anchor slabs embedded in earth fill. The structure maintains itself in equilibrium through soil-structure interaction. In comparison with masonry retaining walls, the anchor slab structure is very light and comparatively flexible. It is especially suitable to be adopted in regions of low bearing capacity. The principles of the equilibrium and stability analysis of anchor slab structures are presented hereof. Finally, the results of monitor observations on some of these structures are mentioned briefly.
