针对周边环境与地质条件均复杂的某校区教学楼与宿舍楼基坑开挖项目,通过人为创造相对自由薄弱面、配合大孔径小药卷不耦合装药,并选取适合的抵抗线大小及方向,进行浅孔岩土爆破;同时,利用现有裂隙、溶洞地质条件降低爆破振动对周边保护物的危害,并采取相关保护措施确保项目稳定实施。此爆破方案改变了传统岩土爆破模式,为类似复杂环境下的爆破提供了新思路、新参考。

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.
