| Abstract | The project under study is the construction of the 22 km long MRT Blue Line ISP in Bangkok which offered engineering challenges due to the difficult geology of the Chao Phraya alluvial flood plain and overcrowded inner city location. This thesis study reviews and evaluates the performance of shield tunnel excavation work of the project where eight earth pressure balanced (EPB) type tunnel boring machines (TBM) were used for two tunnels of Southbound and Northbound tracks. Although this thesis presents the applied tunnel operations and the performance of the shield machines in Bangkok's subsoil. Penetration and advance rates were collected and calculated and show that the tunnel progress was in accordance with the predicted advance rate of 400 m/month for each TBM. A comprehensive instrumentation program was conducted and the collected data shows that the surface and subsurface settlement induced by tunnelling in different clay and sand layer were not too excessive. The average volume of ground loss (V L) was about 1.0 to 2.0 percent, except for excavations in dense sand layers where the .conesponding ground loss was about 3.0 percent of the tunnel volume. The results of ground movement induced by tunnel boring machines in MRT Blue line ISP are summarized in this research. |
