Abstract：In the bustling urban district of Qingdao,a large-area factory buildings need to be demolished by blasting in the information industrial park.The factory buildings are a large-span dense pillar structure.The surrounding environment of the factory buildings to be demolished is relatively complex,which are located in a bustling urban area,with high-rise residential buildings,an in-park substation,an in-park underground utility tunnel,high-voltage power line towers,and a cross-sea bridge nearby.Because the substation within the park has high vibration requirements,the final collapse method adopted is in-situ collapse with a slight tilt to the south.By reasonably using segment delay of detonator,reasonable hole arrangement and network connection,the collapse direction of the factory buildings is controlled.Due to targeted protective measures for flying debris in the surrounding complex environment,the building collapses to the direction designed,without affecting the surrounding park pipelines,high-voltage power line towers,and high-rise residential buildings.This blasting demolition project provides references for the blasting demolition of similar factory buildings.
