Application of shallow hole controlled blasting technology in foundation pit excavation projects under complex environmental and geological conditions
Aiming at the foundation pit excavation project of a campus teaching building and dormitory building with complex environmental and geological conditions,shallow hole geotechnical blasting is carried out by artificially created relatively free weak surface,cooperating with large aperture and small cartridge decoupling charge,and with selecting suitable resistance line size and direction.At the same time,the existing geological conditions of cracks and karst caves are used to reduce the harm of blasting vibration to surrounding protection objects,and relevant protection measures are taken to ensure the stable implementation of the project.This blasting scheme has changed the traditional geotechnical blasting mode.And it provides new ideas and new references for blasting in similar complex environment.
