High Fill Embankment Culvert Vertical Earth Pressure Traits Pilot Study

Based on the concrete engineering of the culvert under the embankment of the high-stacked soil in north second ring highway of Guang Zhou city, the paper researches the soil pressure distribution and change characteristic through on-the-spot arrangement of the test component. The paper also adopts elastic-plastic constitutive model and analyzes the soil pressure distribution and settlement performance with the aid of Marc program, and contrasts with the test results on the spot, the research results have instructive function to the design and construction of the culvert. On the basis of this, the paper puts forward the effective measure of reducing the vertical soil pressure on the culvert.
