某水泥厂矿山竖井发生严重垮塌导致无法使用。通过综合分析对比,并基于二维有限元数值模拟,确定了钢模板+钢筋混凝土衬砌(内模法)+锚杆(土钉封堵法)+锰钢护筒(护筒跟进法)的修复及加固方案。该方案的成功实施验证了其可行性,可作为矿山竖井修复、加固工程中的成功案例。
A cement plant shaft serious collapse caused by unusable. Through comprehensive analysis and comparison, and based on two-dimensional finite element numerical simulation, the effects of steel formwork + reinforced concrete lining (internal mold method) + bolt (earth nailing method) + manganese steel casing (casing follow-up method) Repair and reinforcement program. The successful implementation of the program verified its feasibility and can be used as a successful case in mine shaft repair and reinforcement projects.
