In bored tunnel design, most recent structural design models for tunnel linings concentrate on the behaviour of the tunnel lining in the long-term. The load on the tunnel lining in these models is derived from the original soil stresses, often simplified for a single homogeneous layer. Field observations show that higher loads may occur in...

The current article presents a case study of the settlement response of the historic Hoca Pasha Mosque that involves uncertainties arising from the complex excavation activities, soil properties, building materials, and geometry and the presence of pre-existing cracks in the mosque’s walls. The objective is to demonstrate the added value of a...

Single layer concrete armor systems are being widely used nowadays in the design of rubble mound breakwaters. Recently, a new concrete armor unit has been developed and applied as single layer armor system in the repair works of one damaged breakwater at Al Fujeirah, UAE. It has a symmetrical shape, in contrast to most other units. Modern...

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...

Generally, studies on structural design for bored tunnels focus on moderate to deep tunnels (cover-to-diameter ratio C/D ≥ 2). Such tunnel design methods cannot be used for shallow-situated bored tunnels because the influence of buoyancy is discounted, and actual loads on the tunnel lining are not taken into account properly. This paper...

Geo-energy infrastructure, such as ground source heat systems (thermo-active structures), induce thermal cycles that can result in changes of the bearing capacity of soil by changing, for example, the void ratio, soil structure, unit weight and hydraulic conductivity. The influence of repeated freeze/thaw (FT) cycles and different freezing rates...

The extent of the influence zone affected by shallow tunnelling depends on the value of volume loss which normally represents the amount of over-excavation and stress changes induced in the soil. This paper combines upper and lower estimates of volume loss for different soft soils and cover-to-diameter ratios in order to identify the extent of...

In estimating the effect of tunnelling on existing buildings, the value of volume loss, which is often determined by experience, is an important input parameter. This paper proposes a method to predict the volume loss for various cover-to-diameter C/D ratios in case of shallow tunnelling. By applying a number of (empirical) relation, such as the...

Distributed temperature sensing (DTS) can be used to monitor the production process of diaphragm walls. DTS is able to differentiate between already present or fresh bentonite suspensions during refreshing of the bentonite slurry in the trench. During concrete casting, DTS is able to differentiate between the bentonite suspension and concrete...

The extent of the influence zone affected by tunnelling depends on the amount of over-excavation and stress changes induced in the soil, normally represented as a value of volume loss. This paper combines upper and lower estimates of volume loss for different soil conditions and cover-to-diameter ratios in order to identify the zones around the...

Assessing the impact of underground construction on existing
structures in urban areas is an important topic during design. In this paper, the extent of the effect area due to tunnelling is estimated, where existing foundations are influenced based on the investigation of surface and subsurface settlements. The extent of the areas where...

A new and symmetrical single layer armour unit, the crablock, has been designed in the UAE. One breakwater was reconstructed with crablock, but very limited testing had been performed. Just to become more acquainted with this new unit, pre-competitive research at a university has been performed, which is the subject of this paper. Being a new...

Flow processes, taking place during the concreting of diaphragm wall panels (D-wall panels), are of great importance for the quality of the wall. During this phase, the bentonite, present in the excavated trench, should be completely replaced by concrete in a controlled way. In literature several cases are described in which this process...

If a calamity with a retaining wall occurs, the impact on surrounding buildings and infrastructure is at least an order of magnitude more severe than without the calamity. In 2005 and 2006 major leaks in the retaining walls of underground stations in Amsterdam and Rotterdam occurred. After these cases had been thoroughly studied it was concluded...

As part of the Dutch national research program GeoImpuls an inventory has been made of the state of the education at Dutch institutes of higher education and post-graduate education in so far as this education concerns geotechncial engineering and geotechnical risk management. Significant differences have been found in the amount of time...
