In the field of tunnel construction several attempts have been made to substitute the much more economical reinforced-concrete tunnel liners for cast iron and steel linings. Adequate connexions and problems related to watertightness posed many difficulties, which generally resulted in segments that were too complicated and heavy. A new design of precast-concrete tunnel liners that was developed in Hungary has solved these problems. The development of a deformable hinged tunnel lining system with dowel-type connexion on the one hand, and the decrease of bending moments as a result of the good interaction of the lining and surrounding soil on the other, gave a very small wall thickness. Numerous tests for load-bearing capacity, accuracy and watertightness have shown that the lining withstands the forces that act on it and meets the technological requirements. Detailed information is given on the new precast tunnel lining system and the tests for bearing capacity of the hinges, as well as on precasting of the segments, erection and grouting. Geological and structural details of the use of the system in soft, water-bearing layers, especially in the construction of the Budapest metro, which was awarded the "golden trophy of the europrefab", are also presented. A short account follows on the use of the system in the construction of the Prague metro and the new Belgrade railway tunnel.
