Original Abstract

The research campaign aimed on the better understanding of behavior of prestressed soil anchors in neogene clay, including conduction of variety of in-situ (CPT, PMT) and laboratory (Triaxial test, Simple shear test an Oedometric test) ground investigation methods, has been done during 2012 – 2015 in Czech Republic. The stress – strain diagrams and distribution of axial force along the anchor free length and anchor bond length was determined, based on the data obtained from variety types of sensors placed onto the tendon and into the gravity and post-grouted part of the grout body. On the basis of this information the software application for prediction of the anchor pull-out force and stress-strain diagram was developed, calibrated and verified. The application for purposes of conduction of prestressing tests and test reports elaboration was programmed also. Research activities leading to development of the pair of forenamed software are described in paper.
