Kentucky Transportation Center Research Report
The study of earth pressure distribution on buried structures has a great practical importance in constructing highway embankments above pipes and culverts. Based on Spangler’s research, the supporting strength of a conduit depends primarily on three factors: 1. The inherent strength of the conduit; 2. The distribution of the vertical load and bottom reaction; and 3. The magnitude and distribution of lateral earth pressures that act against the sides of the structure. Rigid culverts are frequently used in Kentucky for routing streams beneath highway embankments because of rolling and mountainous terrain, numerous streams, shallow depths to bedrock, which creates unyielding …
