In Gruwez et al. (2025) werd reeds een evaluatie gemaakt voor een levensduur van 30 jaar maar de evaluatie wordt uitgebreid voor een langere levensduur van de sluis. Het huidige rapport is een update van het rapport van Gruwez et al. (2025) met beschouwing van extra en langere levensduren: 50 en 100 jaar.<br>Indien de maximale kombergingscapaciteit van het Mercatordok wordt aangewend, zijn de minimale kruinhoogtes voor de sluisdeuren van het benedenhoofd +7.05 m TAW (tot 2055), +7.20 m TAW (tot 2075) en +7.80 m TAW (tot 2125). Dit is enkel mogelijk indien het waterpeil in het Mercatordok vóór de storm verlaagd wordt naar +3.30 m TAW.<br>Indien er geen overloop door een hoger waterpeil in het Montgomerydok wordt toegelaten en de komberging van het Mercatordok enkel wordt aangewend voor de golfoverslag over de sluisdeuren en de aangrenzende stormmuren, worden volgende kruinhoogtes voor de sluisdeuren van het benedenhoofd aanbevolen: +7.35 m TAW (tot 2055), +7.52 m TAW (tot 2075) en +8.10 m TAW (tot 2125).<br>Zowel het beton van de beide sluishoofden als de betontegels in de sluiskolk kunnen weerstaan aan de stroomsnelheden nabij de bodem bij het overstromen van de sluisdeuren. Geen informatie is gekend met betrekking tot de bodembescherming naast het bovenhoofd van de sluis in het Mercatordok. Vermoedelijk is deze wel aanwezig. Aan het einde van het bovenhoofd worden stroomsnelheden nabij de bodem berekend tot 1.70 m/s bij een maximale overloophoogte van 0.30 m. Om te weerstaan aan deze stroomsnelheden is een breuksteensortering 5-40 kg nodig.","BibLvlCode":"MS","StandardTitle":"Toetsing op hoogte Mercatorsluis voor langere levensduur: overloop, golfoverslag, komberging en stabiliteit bodembescherming","OrigTitleLangCode":"nl","OrigTitleLangCodeExtended":"dut","OrigTitleLangID":41,"DateLastModified":{"date":"2026-10-24 01:48:12.117535","timezone_type":1,"timezone":"+02:00"},"AuthorKeywords":"Overloop; Komberging; Mercatorsluis","OtherDescriptors":null,"Notes":null,"AnaPub":null,"MonPub":2026,"DateUpdate":"2026-10-23","DateCreate":"2026-10-23","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":null,"monrec":{"MonID":450203,"ISBN":null,"PubliDate":2026,"IssueDate":null,"Volume":"26_035_1","Issue":null,"Pagination":"VII, 39 + 2 p. bijl.","Place":"Antwerpen","Edition":"Versie 4.0","BRefXtra":null,"BRefXtraRR":null,"SerID":24938,"SerRR":"WL Rapporten.
