The　mesh　structure　based　on　double-twisted　hexagonal　grids　is　an　important　part　of　reinforced　gabion　structures.　Due　to　challenges　in　sensor　placement　during　physical　experimentation　on　complex　gabion　mesh　mechanical　properties,　numerical　simulation　serves　as　a　valuable　means　of　study,　with　accurate　numerical　grids　being　integral　to　obtaining　reasonable　results.　Focus　on　addressing　the　limited　availability　of　three-dimensional　numerical　models　for　gabion　meshes,　thereby　offering　potential　for　further　research　on　the　mechanical　properties　of　gabion　structures　under　complex　working　conditions,　the　construction　method　of　three-dimensional　finite　element　model　for　gabion　meshes　was　studied.　Based　on　SolidWorks　software　platform,　a　novel　approach　was　proposed　for　constructing　a　numerical　model　that　incorporates　unique　geometric　features,　in　which,　the　mesh　wires　were　categorized　into　three　groups　based　on　their　geometric　structure　and　a　relational　equation　was　presented　governing　the　motion　of　a　single　wire　axis　during　manufacturing.　Secondly,　a　three-dimensional　finite　element　model　of　a　double-twisted　hexagonal　mesh　was　constructed　using　ABAQUS　software　to　simulate　a　quasi-static　uniaxial　tensile　experiment.　Finally,　the　proposed　approach　was　validated　by　comparing　the　numerical　results　and　the　experimental　results,　supporting　its　rationality.
