| 摘 要： | 借助虚拟力与积分变换法,推导出不均匀弹性及黏弹性岩土介质的边界积分方程和数值求解方法。该数值解法与均匀弹性体边界元法相类似,不需作分区组合计算,也不必随时间逐步求解,简化了计算程序,减少了计算工作量。简述了该方法在岩土工程中的应用。

| Abstract: | The boundary integral equations of inhomogeneous elastic and viscoelastic soil mass were derived through the use of fictitious forces and integral transformation technique. The numerical method for solving these equations was described. This method is analogical to the boundary element method for homogeneous elastic solids. It does not require to solve the problems by zoning technique and time steps so that the solution scheme is simplified and calculations can be largely reduced. The application of this method to geotechnique was briefly presented in this paper. |
