چکیده مقاله
Project and Geology The project is an important link of the main, east west European railway line from Paris to Budapest It consists of the section Stuttgart 21 and the line from Wendlingen to Ulm More than 100 km of tunnels are presently under construction in various geological formations for this outstanding project 2 Tunnel to Bad Cannstatt The conventionally driven tunnel from the new station in Stuttgart to the suburb Bad Cannstatt is mainly located in leached Gypsum Keuper Many buildings are underpassed by the two single track tubes of this tunnel For one example the prediction of subsidence and the comparison with the results of monitoring are outlined 3 Fildertunnel The lower section of the Fildertunnel, which connects the main station with the airport of Stuttgart is presently driven by a TBM through the lower section of the Black Jurassic and through all layers of the Keuper formations Special emphasis is placed on the sections located in swelling Gypsum Keuper and in the claystones of the Black Jurassic formation 4 Tunnel to Ober / Untertürkheim For this conventionally driven tunnel the intermediate access shaft and tunnel are of special interest and are therefore included in the presentation 5 Steinbühltunnel The Steinbühltunnel is located in limestone of the White Jurassic formation, which in the geological past has beensubjected to Karstification Also the conventionally driven tunnel may be of interest for the Iranian engineers 6 Bosslertunnel The two, single track tubes of the Bosslertunnel climb up the Swabian Alb mountains and are excavated by a TBM within the claystones and sandstones of the Black Jurassic formation In the upper section it also penetrates the lower part of the White Jurassic formation Here in a certain section squeezing rock was anticipated To verify the rock mechanical parameters evaluated within the exploratory phases before tendering, an exploratory shaft and gallery have been excavated in an early phase of construction The results are included in the presentation
