Zusammenfassung: | The invention discloses a blasting noise and shock wave control safety construction method for a tunnel adjacent to a residential area, and aims at effectively absorbing or blocking noise and air shock waves generated in blasting construction in a blasting area so as to reduce the influence on a non-blasting area, namely the adjacent residential area. The safe construction method comprises a preparation working stage, a tunnel hole entering mechanical excavation stage and a tunnel hole body sound insulation and wave resistance controlled blasting stage, the sound insulation and wave resistance controlled blasting stage of the tunnel body comprises the steps that blasting parameter dynamic design needs to be carried out before blasting operation, influence partition evaluation is carried out according to a preliminarily determined blasting scheme, drilling and blasting construction is carried out after the blasting scheme and influence partition control measures are determined, and field monitoring is synchron |
