Study On Properties Of Stress,Deformation And Reducing-Pressure Mersure On The High-Stacked Culvert

Based on the concrete engineering of the culvert under the embankment of the high-stacked soil in the highway of Guang An to Nan Chong city, the paper researches the soil pressure distribution and change characteristic through on-the-spot arrangement of the test component. According the field test of culvert with high embankment, this paper states the main cause of culvert damage is that the formula or the experience curves with a smaller earth. Value of the top of culvert from calculation are used. In order to get rid of the damage ,the better means is that soft material- EPS paved on the top of culvert. Its deformation is bigger than stacked soil. This means can mainly reduce the vertical earth pressure. This paper also states that the relation of the height of stacked soil. Different soft material and the best effect of reducing pressure. Numerical simulation analysis about the soil pressure distribution and settlement performance was performed using elastic and elastic-plastic theories with commercial finite element analysis software-MARC and ANSYS, 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.
