摘要
将接触问题与摄动随机有限元法相结合得出了接触问题的摄动随机有限元增量方程.并利用该方法,针对岩层随机移动变形作用,考虑地基基础上部结构的共同作用,对矿区建筑物进行分析.结果表明该方法更加准确完善,特别是对于基底接触情况和基底反力(接触荷载)的计算,结果更加可靠.
By combining contact problem with P. S. FEM, the P. S. FEM increment equation of contact problem is obtained in this paper. In view of random movement and deformation of rock strata, also considering the interaction of ground-foundation-building, a building in mining area is analyzed by using this method. The results indicate that this method is more accurate and perfect, especially in the calculation of Contact condition and counterforce ( contact stress ) of foundation bottom and ground, which the result is more reliable.
