摘要: 首次应用数值模拟方法对煤矿栈桥发生较大量下沉、倾斜问题进行建筑病害分析,提出柱基下预压托换桩和斜撑架断柱相结合的综合顶升纠倾法治理方案。结合结构性能分析,给出顶升纠倾的转动轴位置、柱体断口位置、加载点布置、加载及位移控制量确定的设计要点,并用数值模拟方法予以验证,使后续施工达到预期目的。Abstract: Based on analyzing the reason of the settlement and slope of transshipment gallery in coalmine, numerical simulation was firstly used in analyzing the damage of the building and comprehensive uplifting underpinned piles under column foundation and intercepting brace columns. With analyzing structural function, rotating axis, the intercepting position of column, loading point layout and the decision of load and displacement value were stated. Numerical simulation method was used to prove it. Expected targets were achieved in post construction and good effect of treating the specific structure was obtained.
