| 摘 要： | 引入虚拟力影响项改造均质岩体的边界积分方程,使其满足复合岩体分区介质的边界条件和区界联结条件,采用样条插值函数将分区介质的边界积分方程离散为代数方程组。通过对分区介质样条边界元列式方法的改进,最终使总体系数矩阵成为带宽很窄的条带阵,提高了计算精度和解题效率并应用于平顶山五矿复合围岩的变形分析和支护结构的受力计算。

| Abstract: | By using influencing factor of fictitious force to reform the boundary integral equation of homogeneous rocks, the equation met the boundary conditions of subarea media of complex rocks. Then the equation was dispersed into algebraic equations with spline function. By the improvement of the formulistic method for spline boundary element, the whole quotient matrix was turned into a strip, which had a very narrow strip width. The calculative precision and efficiency to solve problems were improved and successfully put into the practice Pingdingshan No.5 Mine. |
