摘要
近二十多年来，我国广泛采用了有限元法进行重力坝坝体应力分析，但未制定用此法分析时的应力控制标准，使该法计算结果的应用受到限制。本文通过算例与工程实例的分析。
In China,the stress control standard by analysis with FEM has not been layed down,so the application of calculation results is restricted.Through analysing the calculation and project examples,the paper preliminarily presents the relative width of vertical tensile stress distribution at upstream part of dam foundation surface as the stress control standard by gravity dam stress calculation with FEM.
