有限元法用在大坝设计计算中,目前还有一些问题因无章可循急待解决和统一。本文针对计算分析中就坝与基础联合作用;角缘应力失真及如何进行表征等问题作一粗浅的探讨。对角缘单元尺寸提出相对划分标准,以便不同计算成果进行比较。 一、前言 有限元法用于坝工设计计算已有多年历史,随着计算机(特别是微型机)的普及和计算程序不断完善,有限元法的优点体现的越来越显著,广泛应用于工程设计中,并已取得巨大经济效益。
Finite element method used in dam design and calculation, there are still some problems due to lack of urgent need to be resolved and unified. In this paper, we discuss the joint effects of dam and foundation, the distortion of corner edge and how to characterize the problem. Diagonal edge cell size proposed relative division criteria, in order to compare the results of different calculations. I. INTRODUCTION Finite element method has been used in dam design calculation for many years. With the popularization of computers (especially micro-computers) and the continuous improvement of calculation programs, the advantages of finite element method are more and more obvious. They are widely used in engineering Design, and has made great economic benefits.
