This pa per has analyzed shock wave cut role of gear wave wall to explode in air. As a r esult,the gear wave wall of certain alti tude and thichness repairing around the blast source can weaken the pressure of peak value 20%～30% away from air shock w ave after the wall.At the same time,the interaction course between shock wave an d gear wave wall has been calculated wit h numerical simulation method, and the e xplosive site initial development of bar rier around the blast source,as well as entire spread course has been got. Numer ical simulation result basically coincid es with experiment measuring result and experience formula calculating result. T he method can be used to make risk evalu ation on alleviating the injury that une xpected explosive and explosive accident may occur for building and human body.
