摘要

边界积分方程法给出了与降低问题维数相关的效率。本文用边界积分方程法研究了流动自由面和盐鲜界面的非定常行为。阐述了求解运动界面动力学的公式和数值离散化技术,并将理论结果与一些实验结果进行了比较,以检验数值计算的适用性。从实际应用出发,分析了沿海含水层堆垛人工用地和岩洞两个问题。通过多次分析,证实了边界积分方程法在分析运动界面及界面特性方面的适用性。

Unsteady Dynamic Analyses of Free Surface and Under ground Fresh-Salt Interface by Means of Boundary Integral Equation Method and Their Applications to Field Problems
The boundary integral equation method gives the efficiencies associated with the reduction of the dimensionality of a problem. This paper deals with the unsteady behavior of moving free surface and fresh-salt interface on the basis of the boundary integral equation method. The formulation and numerical discretization techniques for solving the dynamics of moving interface are explained, and theoretical results are compared with some experiments to examine the applicability of numerical computation. For the sake of practical use, two problems concerning an artificial land and rock cavern for stock piling are analized in coastal aquifers. As a result of serveral analyses, the applicability of boundary integral equation method for analyzing the moving interface as well as the characteristics of interface are confirmed.
