摘要
以窑街三矿 1 50 0混凝土结构副大巷多层急倾斜煤岩层中复杂结构为研究对象 ,应用三维有限元模型 ,结合现场矿压观测结果和相似材料模拟试验结果 ,对该巷道内部应力破坏敏感部位的内力和变形机理进行了系统的研究 ,得到了非常直观的可视化计算结果 ,这对现场支护设计、维护加固和提高岩层的“凝聚力”
Taking the 1 500 auxiliary concrete structures roadway which has just a few multiple diploid strata as a research object,by terms of utilizing the 3D FEM model,integrating the observation result and resemble simulacrum ending,comprehensive research on the inside of stress distortion and its mechanism are developed,an extraordinary fairly visual result is gained which has an important support in practical supporting design,reinforcement,enhancing the strata cohesion and intensity.
