Choice of rock excavation method for tramway tunnel in Zurich
Summary Within the city of Zurich a new tramway line is under construction. One section consists of a tunnel, 350 m long, which is to be built undergound. Different rock excavation methods were evaluated for this tunnel in the light of the many constraints given by the urban environment, such as disturbance of residents in nearby residential houses and closeness of other structures (bridges, road tunnel, university laboratory with vibration-sensitive equipment, etc.). The excavation methods considered were blasting, hydraulic hammer, bulldozer with ripper tooth and mechanical boring with roadheader. The evaluation was made on the basis of vibrations and noise caused by the different excavation methods and on the basis of their respective construction time and cost. Finally the decisions which led to the choice of the excavation method and to the instructions in the tender, documents are presented, and first experiences from the site are discussed.
