In order to avoid the usage of temporary constructive steel frames, Z.has been working on the design of a new supporting system for openings in tunnel linings; it is a high-performance coupling system for tubbings. One model of this new coupling system was built and tested in the laboratory. Its response exceeded the expected peak load by far in the laboratory test.
