ABSTRACT
The paper is concerned with an anchoring system of a pressure pipeline, using a series of plates and friction piles in foundation soil of poor geotechnical quality. The solution illustrated here was employed for restoring the outlet of a tunnel section of the water mains following a burst caused by the faulty interaction between the existent anchoring block and the foundation soil. The rock formation concerned is composed of tuffites whose mechanical properties were further deteriorated by water spilling from the burst mains. The investigation which led to the remedial action suggested and the advantages achieved are discussed in the present paper.
