The aim of this thesis is to investigate the behavioral differences of walls that have different load transfer mechanisms and identify a simple engi- neering model for a construction joint that connects these two different wall types.<br/>Within the text; First, the problem description is provided among with a simple yet reliable soil modeling...

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...

This thesis aims to analyse the conservatism in the current Dutch recommendations on the external friction angle 𝛿 of diaphragm walls: 𝛿 = 𝑚𝑖𝑛[𝜙, 20°] (for curved slip surfaces) (CUR/COB, 2010), by means of an experimental investigation. Based on literature, two sources of conservatism are identified: 1) filter cake contamination by excavated...

A hot topic in the Netherlands is the safety reassessment of dikes. Currently several (river)dikes are being reinforced to withstand a given normative high water level. The environment of those dikes is often characterised by small floodplains and urban areas right next to the dike, wherefore standard geo-technical measures cannot be applied....

For a safe structure design standards mainly emphasize on calculations based on the uncracked and fully cracked stiffness of concrete structures. In the common design practice an uncracked stiffness (EI0) is applied for the SLS and a fully cracked stiffness (EI?) for the ULS, where the reduced stiffness EI? ? 1/3EI0. However, in reality it is...

Diaphragm walls are potentially ideal retaining walls for deep excavations in densely built-up areas, as they cause no vibrations during their construction and provide structural elements with high strength and stiffness. In the recent past, however, several projects using diaphragm walls as soil and water retaining elements have encountered...

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...

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...

In the preparation and construction stages of the underground car park beneath Kruisplein with diaphragm walls, risk management played an important role. After a description of the structure and the construction, the preventive measures that were invented and carried out are summarised. These relate to the organisation of the project ...

During a design process the risk profile of a project continuously evolves. Often a project progresses through a diamond shaped risk envelope. The initial concept is simple, but during the engineering process several risks are defined and mitigated, making the design increasingly complex. With additional investigations and calculations, some of...

A diaphragm wall is a cast in-situ reinforced concrete retaining wall applied in, among others, quay walls. The main advantages of this type of retaining wall are that it can be made in almost every preferred length and that it can resist high structural loads. However, there are several disadvantages: sufficient concrete cover on the...

In this thesis the impact of an earthquake on quay walls located at the Euromax terminal of the Port of Rotterdam is analyzed. A quay wall is a soil retaining structure where ships can moore and transfer goods. Seismic behaviour of two different types of quay walls are investigated and compared by performing a seismic analysis on the Euromax...

This report is part of my master thesis research for the master ‘Underground Space Technology’ at the faculty of Civil Engineering and Geosciences at Delft University of Technology. Recent calamities e.g. at Vijzelgracht station, part of the North/South line in Amsterdam, triggered the need for research on diaphragm walls and the occurrence of...

Er is onderzoek gedaan naar de technische en economische haalbaarheid van voorgespannen diepwanden. Binnen enkele randvoorwaarden, blijkt het goede mogelijkheden te geven om de zettingen van de belendingen tot een minimum te beperken.

The excavation of deep building pits often requires a check against failure by uplift of low permeability ground layers below excavation level. Whenever the weight of these soil layers is less than the pore-water pressure underneath, measures to resist buoyancy are to be considered. The measures most commonly adopted include: decreasing the...
