The invention discloses a cushion protection rope with fractionated cracking and a preparation process thereof. A rope is woven by 10 low-extension twisted rope strands (1) and 2 high-extension braided rope strands (2), wherein half of the low-extension twisted rope strands (1) are in S direction, while half of the low-extension twisted rope strands (1) are in Z direction; a plurality of braided ropes are arranged in parallel in the high-extension braided rope strands (2), and the elongation at break of the high-extension braided rope strands (2) is at least 8 percent higher than that of the low-extension twisted rope strands (1). The rope is broken in several times while enduring overload, big sound is generated in the cracking process for alarming, enough time is provided to carry out emergency treatment for an emergency situation, and the safety of human bodies and equipment can be protected.
