The invention relates to an anti-pulling test system for a rock anchor foundation of a mountain photovoltaic power station and aims at providing the anti-pulling test system for the rock anchor foundation of the mountain photovoltaic power station to effectively test the anti-pulling bearing force of the rock anchor foundation of the mountain photovoltaic power station so as to solve the problems that in an existing anti-pulling testing technology, a system is complex and not suitable for the mountain region. According to the technical scheme, the anti-pulling test system for the rock anchor foundation of the mountain photovoltaic power station is provided with the rock anchor foundation applied to the mountain regions and hill regions, the rock anchor foundation comprises an anchor rod, an anchor rod locking bolt and an anchor rod cushion plate, after being inserted in a rock slope, the anchor rod is solidified and hardened through a mortar anchoring body, and the anchor rod and the mortar anchoring body are fastened through the anchor rod cushion plate and the rod locking bolt which are sequentially arranged in a sleeved manner. The anti-pulling test system is characterized in that the test system further comprises a counter-force unit, a loading unit and a measuring unit. The anti-pulling test system is suitable for the technical field of geotechnical engineering testing and detecting.
