It is expected that by geogrids implementation significant reduction in the downward propagation of stresses will be obtained, which consequently should assure more resilient long-term performance. In this first approach, however, only added value to the confinement level of the ballast layer is analysed, by evaluation of lateral deformations. A case study is related to a part of the Portuguese railway network. The track and the passing vehicle are modelled in commercial explicit dynamics software LS-DYNA. Firstly, the model is validated by comparison with experimental data. Then a fictitious scenario of the same track with a deteriorated region which is further rehabilitated by the geogrid placement is analysed. Different situations are compared in terms of lateral and vertical displacements at several levels, but for simplicity only rail deflections are shown here.<\/jats:p>","DOI":"10.1051\/matecconf\/201821112006","type":"journal-article","created":{"date-parts":[[2018,10,10]],"date-time":"2018-10-10T08:14:10Z","timestamp":1539159250000},"page":"12006","source":"Crossref","is-referenced-by-count":0,"title":["Numerical analysis of geogrid contribution to railway track reinforcement"],"prefix":"10.1051","volume":"211","author":[{"given":"Ant\u00f3nio","family":"Lanca","sequence":"first","affiliation":[]},{"given":"Zuzana","family":"Dimitrovov\u00e1","sequence":"additional","affiliation":[]},{"given":"Madalena","family":"Barroso","sequence":"additional","affiliation":[]},{"given":"Simona","family":"Fontul","sequence":"additional","affiliation":[]}],"member":"250","published-online":{"date-parts":[[2018,10,10]]},"reference":[{"key":"R1","unstructured":"Paix\u00e3o A., Transition zones in railway tracks-An experimental and numerical study on the structural behaviour, Ph.D. Thesis, Faculdade de Engenharia, Universidade do Porto (2014)"},{"issue":"4","key":"R2","doi-asserted-by":"crossref","first-page":"859","DOI":"10.1061\/JMCEA3.0001144","volume":"95","author":"Lysmer","year":"1969","journal-title":"J Eng Mech Div-ASCE"},{"key":"R3","unstructured":"Rodrigues A.F.S., Viability and applicability of simplified models for dynamic analysis of railway tracks, Ph.D. Thesis, Faculdade de Ci\u00eancias e Technologia, Nova University of Lisbon, Portugal (2017)"}],"container-title":["MATEC Web of Conferences"],"original-title":[],"link":[{"URL":"https:\/\/www.matec-conferences.org\/10.1051\/matecconf\/201821112006\/pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,9,3]],"date-time":"2022-09-03T18:40:29Z","timestamp":1662230429000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.matec-conferences.org\/10.1051\/matecconf\/201821112006"}},"subtitle":[],"editor":[{"given":"N.","family":"Maia","sequence":"first","affiliation":[]},{"given":"Z.","family":"Dimitrovov\u00e1","sequence":"additional","affiliation":[]}],"short-title":[],"issued":{"date-parts":[[2018]]},"references-count":3,"alternative-id":["matecconf_vetomacxiv2018_12006"],"URL":"https:\/\/doi.org\/10.1051\/matecconf\/201821112006","relation":{},"ISSN":["2261-236X"],"issn-type":[{"value":"2261-236X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018]]}}}
