Abstract

This paper is to investigate the fracture behavior characteristics of box culvert and incremental crack width of upper slab for the applied loading by the 3-axis loading system. In the 3-axes loading system, loading directions are upper side, left and right side which simulate static traffic load and earth pressure, re- spectively. With the applied load, crack patterns are investigated on the upper slab, left and right wall. Espe- cially, on the upper slab, crack width is measured by crack gage. Based on the experimental results, structural internal force indices of box culvert are estimated quantitatively.
