  abstract  = {Digitale Lehrmaterialien werden seit mehreren Jahren in den Hochschulen eingesetzt und er{\"o}ffnen ganz neue Wege zur Vermittlung des Lehrstoffs. Die Erstellung dieser Lehrmaterialien kann allerdings je nach Art und Qualit{\"a}t sehr zeitintensiv sein und f{\"u}r Lehrende einen großen Mehraufwand bedeuten. Im Rahmen eines Kooperationsprojekts zur Erstellung von Lehrvideos f{\"u}r geotechnische Feld- und Laborversuche haben die Autoren dieses Beitrags allerdings die Erfahrung gemacht, dass das gemeinsame, hochschul{\"u}bergreifende Erstellen von Lehrmaterialien viele Vorteile mit sich bringt. Dadurch inspiriert, f{\"u}hrten die Autoren dieses Berichts eine Umfrage unter den deutschsprachigen Geotechnik-Lehrst{\"u}hlen der (Technischen) Universit{\"a}ten und (Fach-)Hochschulen durch. Nach drei Semestern, in denen Lehrveranstaltungen an den Hochschulen aufgrund der Corona-Pandemie {\"u}berwiegend digital durchgef{\"u}hrt werden mussten, war es ein Ziel dieser Umfrage, den Bestand und den Einsatz digitaler Lehrmaterialien im Fachgebiet Geotechnik zu erheben. Ein weiteres Ziel war die Initiierung eines Netzwerks, in dem sich Geotechnik-Professorinnen und -Professoren zu Lehrthemen austauschen k{\"o}nnen und gemeinsam (digitale) Lehrmaterialien erstellen und nutzen. Der vorliegende Beitrag stellt das gemeinsame Lehrprojekt der Autoren vor, pr{\"a}sentiert die Ergebnisse der durchgef{\"u}hrten Umfrage und berichtet {\"u}ber die ersten Aktivit{\"a}ten des neuen Netzwerks.},

  abstract  = {As part of a novel approach to automatic sewer inspection, this paper presents a robust algorithm for automatic flow line detection. A large image repository is obtained from about 50,000 m sewers to represent the high variability of real world sewer systems. Automatic image processing combines Canny edge detection, Hough transform for straight lines and cost minimization using Dijkstra's shortest path algorithm. Assuming that flow lines are mostly smoothly connected horizontal structures, piecewise flow line delineation is reduced to a process of selecting adjacent line candidates. Costs are derived from the gap between adjacent candidates and their reliability. A single parameter α enables simple control of the algorithm. The detected flow line may precisely follow the segmented edges (α = 0.0) or minimize gaps at joints (α = 1.0). Both, manual and ground truth-based analysis indicate that α = 0.8 is optimal and independent of the sewer's material. The algorithm forms an essential step to further automation of sewer inspection.},

  abstract  = {Various models have been proposed for the prediction of the necessary support pressure at the face of a shallow tunnel. To assess their quality, the collapse of a tunnel face was modelled with small-scale model tests at single gravity. The development of the failure mechanism and the support force at the face in dry sand were investigated. The observed displacement patterns show a negligible influence of overburden on the extent and evolution of the failure zone. The latter is significantly influenced, though, by the initial density of the sand: in dense sand a chimney-wedge-type collapse mechanism developed, which propagated towards the soil surface. Initially, loose sand did not show any discrete collapse mechanism. The necessary support force was neither influenced by the overburden nor the initial density. A comparison with quantitative predictions by several theoretical models showed that the measured necessary support pressure is overestimated by most of the models. Those by Vermeer/Ruse and L{\´e}ca/Dormieux showed the best agreement to the measurements.},
