Abstract: As the rapid expansion of urban area, the demand of infrastructure projects has increased continuously, while land area is limited. Therefore, the underground construction has become one alternative. Consequently, shield tunnelling method has become the major construction method in urban area, since this method can minimize ground disturbance and also influence to neighboring structures. This...
Abstract: Shield tunnelling technology has been widely used in soft ground conditions to minimize the ground movement and the damage to neighboring structures around a tunnel. Due to limited underground space in urban area and for saving construction cost, multi circular face shield (MF shield) had been innovated to construct a twin tunnel at once. Furthermore, according to the more severe restriction of...
