When process disturbances occur, workers on the Tunnel Boring Machine (TBM) will need to operate outside safe zones, reducing or eliminating the safety barrier ‘distance’ between them and potential sources of risk. Consequently, disturbances have a higher risk potential than regular TBM operations. By comparing the risks of registered process...

A significant part of the energy consumed during the tunnelling process of Earth Pressure Balanced (EPB) Tunnel Boring Machines (TBMs) is related to the main drive, consisting of a set of motors driving the rotation of the cutting wheel. An energy efficient EPB design requires the optimization of the main drive to avoid over- or under powering...

Tunnel-boring machine (TBM) tunnelling through an aquifer will generate excess pore water pressures in the soil around the tunnel face. Accurately predicting the magnitude of the excess pore water pressures is significant because it directly determines the effective face support pressure. In this study, an analytical solution for transient...

In a bored railway tunnel project in the Middle-East, difficulties in terms of ovalization, water leakages and settlement of several lining rings located in a fault zone were observed at the end of the construction stage. The present research attempted to find the cause for this lining behaviour. The determination of critical loading conditions,...

To fight increasing traffic in city centres, tunnelling can be used to move traffic under the surface of the busy city. However, to prevent damage to the surrounding buildings, the settlements induced by the tunnelling should be kept to a minimum. This thesis researches the influence of the TBM tail void and its grouting process on the...

During the advance of a tunnel boring machine (TBM), the torque applied to rotate the cutterhead must overcome the resisting moments acting on it. Hence, one of the major concerns of TBM design is to determine the torque and power requirements of the excavation machine. The first empirical approach for torque estimation was developed in the 80’s...

Constructing tunnels in soft soil with the use of Tunnel Boring Machines (TBMs) may induce settlements. A considerable amount of the total soil displacements is correlated with the passage of the TBM-shield. Even so, the TBM-induced soil displacements are so far only coarsely correlated to the total settlements. This paper relates the shield...

In this thesis an investigation is performed into the rise of excess pore pressures in front of a slurry tunnel boring machine (TBM) during boring. Accurate prediction of excess pore pressures is particularly important when boring close to foundation piles or when boring with a small overburden. The existence of this phenomenon has been known...

The thesis investigates the mechanical equilibrium of a Tunnel Boring Machine (TBM) driving in soft soil. The interaction between the TBM-shield and the soil is also investigated. The analysis is based on monitoring data gathered during the construction of the Hubertus tunnel in The Hague, Netherlands. The monitoring activities during tunnel...

In the Netherlands, when a bored tunnel has to be constructed, a launch and a reception shaft have to be excavated to guarantee sufficient cover. This is necessary to ensure face stability, prevent uplift and risk of blow out. Moreover, especially in the western part of the Netherlands, the first 10 to 20 meters of soil consists of the Holocene...

When a Tunnel Boring Machine (TBM) is driven in soft soil, the TBM-shield constantly interacts with the surrounding soil profile excavated by the cutting wheel. The interaction pattern of shield-soil interface displacements determines compression and extension sectors in the surrounding soil. Soil compression is generated when the shield...

Fires in tunnels are known for their violent nature, their effects pose a major threat to the tunnel and its users. Protection of the tunnel users against the effects of a fire can be achieved by providing sufficient ventilation combined with prevention of collapse of the tunnel within a period of time. However, tunnel structures are important...

De Boortunnel Groene Hart maakt deel uit van de Hogesnelheidslijn-Zuid (HSL-Zuid. De ruim zeven kilometer lange boortunnel wordt aangelegd door het Groene Hart, tussen de plaatsen Leiderdorp en Hazerswoude-Dorp. De tunnel wordt aangelegd als een zogenaamde monotube, dat wil zeggen een grote diameter (14,5 meter) tunnel met twee rijrichtingen Bij...

Tijdens tunnelboringen onder de Nederlandse bodemomstandigheden wordt gevreesd voor het verschijnsel verweking. Verweking is een verschijnsel waarbij verzadigde losgepakte zandgronden ten gevolge van een belasting overgaan van een stabiele naar een vloeibare toestand, dit als gevolg van een toegenomen poriënwaterdruk welke de effectieve...

Boortunnels en ondergronds bouwen in het algemeen, mogen zich in Nederland de laatste jaren verheugen in een grote belangstelling. In ons land dat steeds voller wordt, en waarin naast groeiende personen- en goederenstromen een verschuiving in de leefbaarheidsnorm zichtbaar is, wordt er bij het oplossen van knelpunten steeds vaker overwogen om...
