Abstract

This repository containsexperimental data from Transnational Access project CentriPlug, as part of GEOLAB initiative. CentriPlug is abbreviated from Centrifuge and Plugging and focuses on evaluating the performance of an innovative, small-scale pile instrumented for plug formation modelling. This device allows continuous monitoring of radial total stress and pore water pressure development during the installation of open-ended pipe piles in cohesive soils. The investigation was carried out in the geotechnical centrifuge to ensure a realistic soil stress condition.The experiments were performed in the 9.0 g-ton, 1.22-meter-radius geotechnical centrifuge. The soil specimens comprised soft to firm clay prepared from a Kaolin KDG powder-water mixture (slurry). The models used two customized open-ended steel pipe piles with external diameters of 26 mm and 30 mm and a thickness of 2 mm. The pore water pressure is captured with optical fibre pressure sensors (OFPS), a transducer used for micro-scale environments. KYOWA strain gage transducers detected the total stresses. The pile installation was conducted under an increased gravitational acceleration field of 50g up to a penetration depth of nearly 90 mm, leaving sufficient time for monitoring the total stress and pore pressure development inside and outside the piles. Additional in-flight testing included T-Bar tests and pile pull-out sequences.&nbsp

Abstract

Structural health monitoring is the process of implementing a continuous damage detection strategy to optimize the inspection and maintenance schedules of bridges, and extend their lifespans. One of the main challenges of automated damage detection is the lack of data on damaged states, which makes it difficult to validate new approaches in the research and development stage. To alleviate this problem, a monitoring campaign on a two‐span test bridge with defined defects is conducted and documented in this article. The bridge is a steel‐concrete composite structure with a length of 30 m, with two primary steel girders and a segmented concrete deck. The recorded data capture the long‐term ambient data from 18 test days and changing environmental conditions, as well as the short‐term ambient data and dynamic load tests from four damage scenarios with well‐defined damage extents. A mobile measurement system with numerous sensors is used for data acquisition. A shaker is placed on the bridge to excite white noise. The main goal of this article is to document the experimental procedure and perform preliminary plausibility checks on the measured data. First results demonstrate that system response data and environmental conditions are recorded reliably and that environmental effects significantly affect the long‐term measurements. Therefore, a suitable data set is provided as open‐source data for future studies on data normalization and automated damage detection. [ABSTRACT FROM AUTHOR]

Abstract

Rail connection of the Fehmarn Belt fixed link – foundation relevant geotechnical special features The rail connection of the Fehmarn Belt fixed link is one of the top 3 railway construction projects in Europe. The aim is to guarantee continuous and fully electrified rail connection between Scandinavia and Germany. In the context of the approx. 88 km long railway, beside the rail track many civil engineering structures are to be constructed. Therefore, for all structures soil investigations are necessary to provide a fundamental basis for the planning process. Thus, for several years extensive soil investigation campaigns are carried out to evaluate the soil conditions in the project area. Due to the glacial history in eastern Schleswig‐Holstein the soil conditions are often very variable and inhomogeneous which leads to big challenges within the planning process. In the present article, the geological and geotechnical challenges in the present project are discussed on the basis of several exemplary situations and some solutions to overcome these challenges are briefly outlined.

Abstract

Numerische Verfahren sind zum Standardprozess in der Untersuchung von geotechnischen Bauwerken geworden. Mit stetig steigender Rechenleistung gewinnen Hybrid- und Kontinuumsansätze, die durch ausgefeilte Materialmodelle unterstützt werden, immer mehr an Bedeutung. Der Workshop „Numerische Methoden in der Geotechnik 2022“ der Technischen Universität Hamburg (TUHH) unter Beteiligung des AK Numerik (DGGT) und der Bundesanstalt für Wasserbau (BAW) bringt internationale Wissenschaftlerinnen und Wissenschaftler und Fachleute zusammen, um neueste Erkenntnisse in Bezug auf die Entwicklung numerischer Methoden in der Geotechnik zu präsentieren und zu diskutieren. Dieser Tagungsband enthält die verschiedenen auf dem Workshop vorgetragenen Themen. Er soll die gewonnenen Erkenntnisse für zukünftige wissenschaftliche und praktische Anwendungen erhalten und sie mit der geotechnischen Community teilen., Numerical methods have developed into standard tools for the investigation of geotechnical struc tures. With increasing computational power, hybrid and continuum-based approaches supported by sophisticated constitutive models are becoming more and more important. The Workshop “Nu merical Methods in Geotechnics 2022”, hosted by Hamburg University of Technology (TUHH) in cooperation with the working group Numerics (AK Numerik of DGGT) and the Federal Waterways Engineering and Research Institute (Bundesanstalt für Wasserbau, BAW), brings together international scientists and experts in order to present and discuss newest findings with regard to the development of numerical methods in geotechnical engineering. These proceedings have been compiled based on the different topics presented in the framework of the workshop. They are supposed to preserve the findings for their future scientific and practical use and to share them with the geotechnical community.

Abstract

A wafer through-hole interconnection method is suitable for electronic circuit fabrication. The method can provide high density three-dimensional (3-D) wiring systems with interconnections of high vertical wiring density. Electrodeposition of photoresist on 3-D micromachined substrates shows that the interconnection line width can be of the order of 20 micrometers. The vertical wiring density can be up to 250 cm(super -1).

Abstract

Numerical investigation on the influence of reaction piles regarding static load test results The present paper investigates the influence of reaction piles on the load‐settlement behavior of the test pile during static load testing by means of a numerical study using FEM. In this investigation mainly the parameters distance between piles, pile length, length of reaction piles in comparison to the test pile's length as well as the number of reaction piles are varied. It is found out that the recommendations of the working group piles (EA Pfähle) regarding the minimum distance between test and reaction piles is not sufficient to avoid an influence of the reaction piles on the test pile's bearing behavior.
