| 摘 要： | 本文阐述了有限单元法求解具有浸润面的土坝三向稳定渗流场的原理和方法。并利用有限单元法的特点给出在均质土坝和非均质土坝上调整浸润面和渗出段的方法和计算任意形状过水断面的渗流量方法。文中还详述了在国产TQ-16型计算机上实现具有一定规模的土坝三向稳定渗流问题有关的技术。最后结合实际工程对均质和非均质渗流场进行了计算分析,经与原体观测资料对比,二者颇为接近,从而为广泛应用电子计算机计算土坝三向渗流问题提供了经验.

| Abstract: | This paper states the principle and method to solve three-dimensional steady seepage flow field with free surface by finite element method and utilizes the characteristics of finite element, method to find out the methods of regulating the free surface&;amp;seepage surface and calculating seepage discharge through water section of any form in homogeneous and heterogeneous earth dams. It also states some techniques of three-dimensional steady seepage flow problem within finite region that being carried out on TQ-16 electronic computer.Finally, by analyzing the homogeneous and heterogeneous seepage flow field associated with engineering practical examples and that in camparison with field data it is verified available. Thus the experience to compute three-dimensional seepage problem by widely applying electronic computer is presented. |
