This report describes the stress characteristics of a culvert type inspection gallery which is constructed on foundation rock. The finite element method is applied to analyse stresses of the cross section of the gallery subjected to embankment load. From these analytical results, the effects of gallery shapes, analytical conditions and foundation properties on the stresses of the gallery are discussed. And the amount of reinforcement required is calculated to prevent occurrence of crack in a section. The crack development and the compressive failure of the reinforced concrete section with increasing loading is also analysed by the nonlinear finite element method.
