The Drainage System In Deformable Slope

The drainage system in the slope has been one of the weak links of the urban drainage system all the time. Main reason is the deformation in the slope which is easy to be produced for the function of the external force. And once the deformation of the slope is took place, the pipeline among them can't fit the amount of the deformation. The drainage system certainly will be destroyed. It will cause serious influence to life and production. At present, the design method of the drainage system is to select the pipe first, calculate through flow and water conservancy calculate and confirm pipe diameter, slope, velocity of flow etc. and then. The drainage system designed through such design thought can't well adapt to the slope deformation. If we choose pipe according to the deformation amount of the slope, and then carry on flow and water conservancy to calculate, the drainage system has well servo ability of deformation. In order to achieve this purpose, the text has carried on the discussion to the tube soil interaction mechanism in the slope plasmodium. While analysis the function mechanism of the pipeline and soil, due to the pipeline one is long and thin, the characteristic of the pipeline is different between axis and section. We'll analysis the deforming of the pipeline form the two aspects in the article. On axis, the deformation way of the slope is divided into towed and pushing type. On section, three kinds of strength that act on the ring of pipe are calculated separately. And then, superpose each result according to the line theory. The ones that combined certain project and carried on actually can be regarded as example analysis. According to different models, we've got the change characteristic of the pipeline deforming. Utilize the large-scale finite element software ANSYS to carry on numerical simulation analysis to several kinds of models among them. According to analysis, we've got the function mechanism between the pipeline and soil, and offered the theoretical foundation of design for the drainage system in the slope plasmodium.
