Abstract
This paper describes the behavior of ground anchorages installed in multi-layered strata under tensile load. It also shows a predicting method of load-displacement and load distribution curves derived from specific differential equations. Displacement and load distribution of anchors computed by the predicting method were compared with the results obtained from pull-out tests of actual anchors installed in a Kanto-loam stratum. There were good agreements between the computed and the observed load-displacement and load distribution curves.
In the end, this paper shows soil constants for the predicting method obtained from pull-out tests at 30 sites, and results of a numerical simulation for a model ground consisting of two strata.
