AB - Conclusions 1. The installation of ground anchors by embedding casings with an IP-4603 pneumatic punch on positioning it in the lower section of the casings provides for quality pressure application of grout in the zone of the anchor's fixity; this leads to a significant increase in the anchor's bearing capacity. 2. The installation of ground anchors by embedding casings with an IP-4603 pneumatic punch, where the latter is positioned on the surface of a guide apparatus, is possible only to a depth of 15 m in loose sandy soils, and to a depth of 10 m in sandy soils of medium density (in the absence of gravel-rubble inclusions). 3. The bearing capacity of ground anchors depends to a significant degree on the method of their installation, and for displacements of 6 mm, amounts to 400–500 kN for anchors installed by positioning the pneumatic punch in the mouth of the hole (method III), and 250–350 kN for anchors installed with the use of auger drilling (method II). 4. According to the results of pretensioning, the anchors lost from 20 to 50% of their initial tension on transferring the tensile force from the hydraulic jack to the tensioned nut; this must be considered in designing and installing anchors. 5. Long-term observations of the tensile force in anchors indicated that these forces are subject to variation. In the initial period prior to constructing the trench, they increased, remaining 25% below the initial force on the average for the majority of anchors.
