The article describes the design and calculation peculiarities of pile-supported retaining structures reinforced with a drill and inject anchors from tubular screw rods. The authors considered two options for this type of anchors setup: without free length and with a pre-set free length. In the software geotechnical complex Plaxis, on the finite element method basis, mathematical modeling and calculation of a pile-supported anchor retaining structure with different free anchors lengths from tubular screw rods for various soils types have been performed. Numerical relationships have been obtained between the anchors&#8217; free length and the resulting forces in the retaining structure. The performed calculations series of the test scheme showed that with an increase in the free anchors&#8217; length in the retaining structure, there is a decrease in the applied load in its load-bearing elements due to the horizontal displacements growth. The article presents the survey results of a real road section, on which a landslide displacement is being prepared, and considers a design solution for a pile-supported anchor retaining structure to ensure its safe operation. Performed a series of calculations for various landslide process development stages in this area showed that the effect of the anchors&#8217; free length also largely depends on the state of the adjacent soil mass. Obtained results clearly show that the design of a free length section for anchors made of tubular screw rods makes it possible to design more cost-effective pile-supported anchor holding structures without reducing their reliability.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords: <\/strong>road; landslides; pile-supported anchor structures; anchor made of tubular screw rods free length of the anchor<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Nikolai N.
