Abstract
The paper presents the results of studies into a curvilinear heaving mound depending on the distance between the fixed supports. To solve this task, three possible versions of the model of a curved section of the main pipeline are constructed considering the distances between the fixed supports and the frost heaving pressure on the pipe supports, which is specified in the range from 0.5 to 4.5 MPa and characterized the heaving area. In the first case, the distance between the supports was set to 100 (145) m, in the second—200 (245) m, and in the third—300 (345) m. Based on the obtained results, graphs are constructed. The dependences of the stresses arising in the pipeline during frost heaving of the soil on the distances between the fixed supports are given. The stress-deformed state of the pipeline is calculated for three versions of the models of the curved section of the main pipeline using the SolidWorks PC. Based on the results of all the calculations of the stress-deformed state of the pipeline with curved sections, a graph of stress versus ground heaving pressures is constructed for three options for installing fixed supports. It was found that the most favorable conditions for operating a curved section of the pipeline in the area of possible soil heaving, from the point of view of the stress-deformed state, are considered to be conditions when the distances between the fixed supports exceed 200 m.
