MEASUREMENTS AND RESULTS OF APPLYING THE GROUND FREEZING METHOD IN TUNNELLING

The 1310m long Milchbuck Tunnel takes the SN 1 expressway under a heavily built up area in the town of Zurich. Problem conditions included non-cohesive silty-sandy material and the presence of water under an artesian pressure of up to 3 bar. This paper describes the constructin method used, which included ground freezing prior to full face excavation; and the lowering and pressure relief of the ground water by means of small bore filter wells.
