Abstract:In order to study the deformation and stress distribution of long-span steel corrugated pipe under the action of high fill, the deformation characteristics and stress distribution of steel corrugated pipe culvert during construction and under vehicle load were analyzed by ABAQUS finite element modeling method. The results show that the steel corrugated pipe culvert has good deformation capacity, and the pipe culvert has small compressive stress on the bottom foundation, and the deformation of the foundation is uniform. Under the action of high fill and live load, the stress at the top of the pipe is the most unfavorable. The influence of vehicle live load on the steel corrugated pipe culvert is smaller than that of backfill. At the same time, under the action of live load after the backfill is completed, the deformation and stress of the steel corrugated pipe culvert meet the requirements of the specification. It can be seen that the large span steel corrugated pipe culvert under high fill is feasible in engineering application, which can provide reference for the practical application of steel corrugated pipe culvert.
