前言有限单元分析法[克拉夫(Clough),1960]已经被应用到一系列土力学和土工问题上。这方法曾用于土坝的应力和变形的分析[克拉夫和伍德沃德(Woodword),1967][芬恩(Finn),1967],计算深开挖四周土的移动[邓肯(Duncan)和邓洛普(Dun-
Introduction The finite element analysis method [Clough, 1960] has been applied to a series of soil mechanics and geotechnical problems. This method was used to analyze the stress and deformation of earth dams [Clav and Woodword, 1967] [Finn, 1967], to calculate the movement of earth around deep excavations [Duncan and Dunlop (Dun-
