Culvert Top Laying Of Flexible Packing Layer Offload The Effect Of Trial

The conduit crack on axial direction is the phenomenon that can often been seen. According the field test of conduit with high embankment, this paper states the main cause of conduit damage is that the formula or the experience curves with a smaller earth. Value of the top of conduit from calculation are used. In order to get rid of the damage the better means is that soft material paved on the top of conduit. Ifs 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. This has a important role to the case of project. This paper analyses the performance of stress and deformation of the conduit through the Marc programme.
