Abstract
In order to estimate the bearing capacity of two types of foundation of the pre-cast arch culvert, two-dimenstional loading test using the aluminum rods modeling ground has been carried out. Through the experimental results and their image analyses, the bearing capacity and the embedded depth in each foundation type have been discussed. As a result, the effect of the embedded depth is defferent as depending on the foundation types. In case of the footing foundation, the bearing capacity is affected by the ground depth located on the inside of culvert. In case of invert type foundation, it is also confirmed that the bearing capacity can be estimated as the embedded depth of the height of the embankment.
