摘　　要：本文针对铜官山饲矿选厂构筑物宏观破坏特征,阐述了在选厂持续生产条件下,采用预应力锚杆、锚轩桩和预预力锚杆井字形混凝土支承梁综合技术加固厂房内侧挡墙以及利用地层锚固力治理厂房地基构筑物损害的研究结果。工程实践表明:该项技术能有效防治构筑物破坏,确保选厂正常生产,取得明显加固效果。On the basis of the macroscopic failure of the structures for the concentrating mill at Tongguanshen Copper Mine, Combined techniques were used for reinforcement of retaining walls in the inside of the building, including the prestress anchor, anchor piles, concrete supporting beams, and remedial measures against the damage of structures and their foundation utilizing the anchoring force of strata under the conditions of continuous production.The engineering practice shows that these techniques can effectively prevent the structures and their foundation from failure and ensure the safe production of the mill.
