유한요소법에 의한 流線網 解析

Abstract

종래에는 流綠網을 作圖함으로써만 얻어질 수 있었던 침투 유출량이나 지하수의 임의의 지점의 유속 ?樗막? 流綠網에 관한 기본 방정식인 Laplace 방정식에 Galerkin 방법을 사용하여 유한요소기법으로 수치해석하였다. Computer Program은 Y.K. Cheung과 I.P. King에 의해 개발된 구조해석 Program을 본 문제에 적합하도록 변형하여 사용하였다.

Seepage problems were usually analyzed by drawing flow nets, but this paper analyzed the problem by applying the finite elements method to the Galerkin's form of the Laplace equation which is basic equation of the flow net. Calculation was done by the finite elements computer program, which was developed by Y.K. Cheung and I.P. King for structural problem, being modified to fit this object.
