Numerical approach for assessment of stress strain state of road culverts

In this issue is considered the developed computational model on the basis of finite element method, which is first of all provided the calculation of stress-strain state of embankment and culverts. This method describes real properties of soils and road culverts of various shapes under effect of transport loads. The comparative analysis of results of model calculations showed the applicability of developed method to carrying out a numerical experiment for structures of culverts. As a result of calculations, the internal forces in structures of culverts (bending moments, transverse and normal forces) and stresses in the soil surrounding of them are determined.
