Analysis of main factors for culvert diseases of high-filled embankment in mountain regions and engineering measures
The main factors are analyzed in the paper for the culvert diseases of high-filled embankment and the main factors affecting the vertical earth pressure of culvert are also analyzed from the perspective of culvert-soil function mechanism & soil arching effect,then the suitable nonlinear formula to calculate such pressure is put forward.In order to reduce the culvert diseases,the simple load reduction measures are proposed.Suitable method of soft foundation treatment is also suggested based on the analysis of influence to the internal forces of culvert structure by the varied elastic modulus of foundation,which will offer guidance and reference for the design and construction of such projects.
