The invention relates to the field of calculation of bearing capacity of civil engineering bridge pile foundations, in particular to a pile foundation rock-socketed depth design method considering the full-life-cycle karst cave corrosion amount of a bridge, which comprises the following steps: 1) respectively calculating the pile foundation rock-socketed depth when the vertical bearing capacity, the pile body stability requirement and the full-life-cycle karst cave corrosion amount are considered; and (2) comparing the pile foundation rock-socketed depth when the vertical bearing capacity, the pile body stability requirement and the full-life-cycle karst cave corrosion amount are considered, and taking the maximum value as a design value. According to the pile foundation rock-socketed depth design method considering the bridge full-life-cycle karst cave corrosion amount, the influence of karst cave corrosion on the bridge pile foundation rock-socketed depth value can be dynamically considered, and a reference
