The invention relates to the field of highway traffic equipment, in particular to a guardrail with compound functions of vibration reduction and disaster prevention. The guardrail comprises an uprightcolumn arranged on a highway, wherein the upright column is connected with a guardrail plate through an energy dissipation device. The guardrail with the compound functions of vibration reduction anddisaster prevention is reasonable in design. On the basis of ensuring the functions of an existing conventional expressway guardrail, the guardrail can reduce the destructive force in the event of acollision, and prevent a vehicle body from bouncing onto other lanes at the same time to avoid a second traffic accident.
