Veringa, Martijn (author)
In this study loading characteristics of rubble mound breakwater crown walls are investigated. This is done using a 2D physical model, testing for overall stability (through sliding) and temporal & spatial distributions of pressure along the face and base of the crown wall. A variety of wave conditions and geometries is used, with special...

Spectral rendering is a crucial solution for photorealistic rendering. However, most available texture assets are RGB-only, and access to spectral content is limited. Uplifting methods that recover full spectral representations from RGB inputs have therefore received much attention. Yet, most methods are deterministic, while, in reality,...

Seismic-induced liquefaction is one of the main hazards for pipelines buried in saturated granular materials. When soil is partially or completely fluidized, a lifeline, although installed in superficial trenches in which the coarse backfill soil usually is compacted, may experience a sudden uplift and damages. To reduce pipeline uplift and...

This research is about which geometry of FRP slabs is the most optimal, in terms of costs, to use for a given load and boundary conditions taking the occurring uplift bolt forces into account. The first part of the report focuses on the calculation of the uplift forces in the bolted connections caused by the moving loads. For this, first a...

After World War II, various architectural theories were proposed for urban development in order to tackle the societal issues and housing issues arising from the post-war trauma. ‘Streets-in-the-sky’, proposed by the English architects Alison and Peter Smithson in 1952, was one of the concepts that emerged in the post-war era and advocated the...

The tunnels located in the shallow depths of loose saturated sand are significantly prone to liquefaction-induced uplift. Research works are, therefore, in progress to propose efficient techniques for mitigating uplift. In this study, 1 g physical modeling was used to assess the performance of helical piles for decreasing liquefaction-induced...

Pit-in-pit (PIP) excavations in an aquifer–aquitard system likely undergo catastrophic failures under the hydraulic uplift, the associated undrained stability problem, however, has not been well analyzed in the past. To this end, a hypothetical model of PIP braced excavation in typical soil layers of Shanghai, China is developed using the...

In the Krafla region in North East Iceland, a change in the deformation pattern was observed in 2018. Since the 1975-1984 rifting event, there was subsidence seen in the Krafla caldera and along the fissure swarm. This subsidence was explained by deflation which decreased exponentially along the years. In 2018, this deformation pattern reversed,...

Internal erosion is a frequent cause of dike failure, also known as piping or backward erosion. Uplift is considered a submechanism of internal erosion, together with heave and piping, where all three submechanisms must occur for the dike to reach a failure condition. The principle of the uplift phenomenon is straightforward: it occurs when high...

Rifting and related normal stress regime in the equatorial continental margin of Brazil ceased during the Late Cretaceous, when the stress regimes in eastern South America and West Africa changed to induce strike-slip or reverse motion. In this study, we explore the postrift tectonic, geomorphic, magmatic, and sedimentary responses to stress...

Crustal rheology and surface processes strongly influence strain distribution and shape of orogenic wedges at their front but how they influence the wedge rear is still unclear. Here, we analyse the coupled control of viscosity and sedimentation on forearc high growth during advanced stages of subduction accretion. We use 2D thermo-mechanical...

With the shift of the safety standards for levees from exceedance probability (standard 1996) to flooding probability (new standard), the part of the levee failure process after the initial occurrence of a failure mechanism becomes more important for the calculation of the strength and thus, reliability of the levee cross-section. Interactions...

In the present study the stability of crown wall elements on top of a rubble mound breakwaters is investigated. The first step was conducting a literature review, in order to identify knowledge gaps. It was found that current design methods do not take the freeboard of the crown wall into account when calculating the vertical force acting on it....

When offshore platforms have reached their end of lifetime, they have to be decommissioned. The topsides will be removed first, whereafter the jacket structure will be removed. Typically, the structure has to be removed up to 3 meters below seabed level. Decommissioning of jacket structures in clayey soils will result in large uplift forces due...

This study considers pipe uplift in liquefied sands in case full liquefaction occurs in the Groningen area. Due to the short vibration time, approximately 2 seconds, uplift is considered in fully liquefied sands without vibrations. The liquefaction time and resistance against uplift are determined by experiments. The resistance against uplift is...

Dynamic analysis of the stinger hang-off system cable forces using ship motion data of Audacia. Already for some time the desire exists to acquire insight into the phenomenon of stinger uplift. This is the situation where external forces and motions acting on the ship, stinger cause the hang-off cables to have no or barely any cable tension....

The traditional Dutch way to deal with piping failure in river dikes is the implementation of piping berms. The disadvantage of such a measure is the required inland space. Relief wells, on the other hand, require less or no inland space representing an attractive alternative solution. The aims of this paper are first, to show how reliability...

A method was developed to identify areas where uplift is likely to occur during sewerage renewal. The results were presented as a map that can be used by generalist civil engineers in the early stage of the sewerage renewal planning process.

This dissertation presents the applications of probabilistic-based frameworks in geotechnical and hydraulic engineering, for the assessment of the Red River dikes in Viet Nam. Dike along rivers often spread over the deltaic environment and its earthen structures are parts of a long civilian history, from hundreds to thousands of years....
