The　rugged　terrain　of　Jiuqu　Plank　Road　experiences　heavy　tourist　traffic　year-round.　To　assess　the　impact　of　tourist　loads　on　rock　mass　stability,　a　refined　model　was　established,　using　numerical　simulations　to　analyze　stress　and　deformation　under　static　and　dynamic　loads.　The　results　indicate　that　when　the　Jiuqu　Plank　Road　is　fully　loaded　with　pedestrians,　the　rock　mass　is　generally　stable,　with　only　partial　damage　to　the　surface　rock　mass.　Under　static　load,　the　surface　rock　mass　of　L1　crack　bottom,　L15　middle　and　lower　parts,　and　the　Buddha　niche　at　the　bottom　of　the　plank　road　are　subjected　to　tensile　failure,　and　the　surface　rock　mass　at　the　two　corners　of　the　middle　and　lower　parts　of　the　plank　road,　the　Buddha　foot　platform,　and　the　protruding　part　facing　the　river　are　prone　to　tensile　failure.　The　vibration　velocities　of　the　rock　mass　in　the　boardwalk　under　dynamic　load　all　exceed　the　specification　allowable　value,　and　it　is　prone　to　fatigue　failure　under　long-term　pedestrian　dynamic　load.　The　surface　rock　mass　at　the　protruding　corner　of　the　upper　part　of　the　plank　road　may　experience　instantaneous　tensile　failure.　These　findings　are　essential　for　monitoring　stability　and　guiding　preventive　reinforcement　efforts.　©　2024　Chongqing　University.　All　rights　reserved.
