EXPERIMENTAL STUDIES FOR THE INTERACTION OF AN UNDERGROUND POLYETHYLENE PIPE WITH SOIL UNDER THE ACTION OF DYNAMIC LOADS USING THE CENTRIFUGAL MODELING METHOD
The article presents the results of experimental studies using the method of centrifugal modeling. The experiments were carried out on a centrifugal installation with an effective radius of rotation R = 1.75 m. The methods for carrying out research under static and dynamic effects on the underground pipeline have been developed. The dependence of the elongation of the polyethylene tube on the temperature at different depths of its location and the pressure change on the pipe is given. Experimental work was carried out to study the effect of dynamic loads on the state of underground polyethylene pipes. The obtained results of the research are presented in the form of graphs and conclusions are drawn.
