The bearing capacity of foundation ground with one layer geogrid is studied on the basis of both laboratory loading tests and theoretical consideration. The test results show that there exists an optimum installed depth of geogrid which a maximum reinforcing effect is mobilized. The depth is about the same value as the width of strip footing, and is independent of the geogrid width and the ground density. A bearing capacity equation is formulated using limit equilibrium method and the validity is examined from the direct comparison between the calculated results and the loading test results.
