Abstract

ESTIMATIONS OF INFLUENCE OF INJECTION ANCHORS ON GEOTECHNICAL PARAMETERS OF SOIL Summary The questions connected with estimations of loading capabilities of injection anchors and influence of these anchors on soil parameters are discussed. The influence was determined in the course of tests made in six test fields situated in areas of the first line and stations of the Warsaw underground. The results of field and laboratory studies made it possible to state that anchors made with the use of the technology adopted in construction of the underground result in some loosening of non-cohesive soils but only in minor changes in properties of cohesive soils.
