从地下厂房布置与地质条件的关系出发,阐述了地下厂房的开挖、支护施工技术与成效,重点研究小夹角陡倾岩层下开挖分层与爆破方式优化、仰角锚索施工技术创新、直立隔墙对穿锚固技术优化、直立高边墙挖空率与围岩稳定的关系等问题,运用数据统计对比进行了分析。本文提出的优化创新技术对土建工程洞室布置、开挖与支护技术应用具有一定的参考价值。
Based on the relationship between the layout of underground workshop and geological conditions, the excavation and support construction techniques and effectiveness of underground powerhouse are expounded. The stratification and blasting mode of excavation under small angle steep rock formation are optimized. , Vertical wall to anchor technology optimization, the relationship between the hollow wall height of upright high wall and the stability of the surrounding rock and other issues, the use of data statistics were analyzed. The optimization and innovation technology proposed in this paper has a certain reference value for the layout of the cavern, excavation and support technology.
