An intervention and repair method of log dry radial shake is characterized by comprising the following steps that 1, logs 1 which have approximate diameters are taken for standby; 2, the logs are cut into log segments with certain lengths; 3, the logs are processed into the cylindrical log segments; 4, a slot is formed in each cylindrical log segment in the longitudinal direction, the depth of the slot is equal to the radius of the log, and the slot is a linear slot with the circle center facing outwards; 5, the slotted log segments are piled, stacked or sent into a drying kiln to be dried, a V-shaped groove cracking linearly in the slotting direction is formed in each log segment, and then each V-shaped groove is cut into a rectangular groove or a new large V-shaped groove; and 6, the rectangular grooves and the V-shaped grooves in the log segments are filled with the same kind of wood to form an integral structure through gluing. According to the intervention and repair method, the log dry radial shake tension can be released in the set direction, the complete round log segments are formed through repairing, and accordingly, the utilization rate of wood is substantially improved.
