Designing challenges engineers to develop both economically attractive and safe designs. This might seem a paradox, but with the application of the observational method, wherein safety is checked by real-time monitoring, economic design and safety are united. The observational method is recently successfully applied in the Netherlands during the...

A new lifting bridge is being constructed crossing the river Oude Maas in the Rotterdam harbour area in the Netherlands. Since foundation deformations of the main piers have a large influence on the performance of the superstructure, extensive deformation analyses have been performed during the design phase. In order to minimise the risks and...

The 2008 Mw 7.9 Wenchuan earthquake triggered at least 257 landslide dams, most of which formed in series along rivers. The failure of an upstream dam could cause the failure of dams downstream one after another. The cascade dam breaching may result in sharp increase of flood and more serious damage downstream. This paper aims to analyze the...

A design scheme is proposed to evaluate the safety of continuous linear structure i.e. river levee. The scheme is developed to establish a procedure to continuously evaluate the stability failure of embankment during flood runoff by seepage, and to identify locations for reinforcement of river levee. A 20km stretch of a fairly large river...

The application of the Observational Method can contribute to an economic construction process and effective geotechnical risk management. Current project management practices and control of construction works lead to unfavourable conditions of its application. Throughout the realization of infrastructure, understanding of project risks and...

Due to hilly terrain and frequent heavy rainstorms, debris flow is one of the most common and catastrophic hazards in Hong Kong. To mitigate the debris flow risk, prediction of the magnitude and consequence of debris flow is essential. The objective of this paper is to simulate debris flow hazards in a study area in Hong Kong. Assessment of the...

In the Netherlands research has been performed on the Observational Method, aiming at a wider use of the method in the design of underground and infrastructural construction works. This paper summarizes the guideline that was output of the research, providing a clear definition, an overview of obstacles and pre-conditions, practical...

For all types of construction works the aspects safety, serviceability and sustainability have to be focused during the planning phase, the design phase, the construction phase and in the service phase. Particularly this has to be considered for complex deep foundation systems like the Combined Pile-Raft Foundation (CPRF). The basis for a...

The A2 tunnel in Maastricht has been built within a dry building pit with a maximum depth of 22 meters with sheet pile walls, suspended in a cement bentonite trench supported by struts at 2 to 4 levels. Dewatering is done by deepwells. The excavation reaches into Limestone layers so the maximum mobilized passive resistance of the sheet pile wall...

During the last decade, at least eight earthquakes occurred in the Northern Netherlands with a magnitude of 3 or higher on the Richter scale. These earthquakes are not tectonic but induced by natural gas production from the Groningen Gas Field. Before that time there were no earthquakes in Groningen with such magnitudes. Research conducted by...

Geotechnical engineering designs are often predefined before construction commences, in an attempt to eliminate uncertainty. Such predefined design can lead to poor value, either due to waste of resources from over design, when opportunities are missed for optimising the design during construction, or due to the delay and additional cost of...

The failure probability of geotechnical structures with spatially varying soil properties is generally computed using Monte Carlo simulation (MCS) methodology. This approach is well known to be very time-consuming when dealing with small failure probabilities. One alternative to MCS is the subset simulation approach. This approach was mainly...

Due to the complexity of natural ground condition, consolidation settlement is usually difficult to predict. In this study, a Pareto multi-objective optimization based back analysis method for consolidation settlement is presented in this study. The model is a coupled flow and deformation model for unsaturated soil foundation which is...

All Eurocodes are currently under a critical review, while the work for a second generation of codes are about to start in 2015. For the geotechnical design EN 1997-1 is facing high demands for harmonization and simplification of the present code. The paper presents some proposals for improving the code regarding ultimate limit state (ULS)...

The statistics course most engineers took in college—seldom more than one—introduced them to a particular species of statistics, which, regrettably, is of limited use in geotechnical practice: frequentist sampling theory. That species of statistical thinking arose to address problems of agricultural experimentation, biology, and economics. It is...
