摘要
探讨拉、压不同模量有限元法在重力坝应力、变形分析中的应用，利用该方法计算坝体裂缝、接触、稳定问题明显地提高了分析精度．本文指出，给定拉伸时的弹性模量和泊松比是重要的和可能的，在岩土力学、冰力学、陶瓷和塑料的力学分析中，使不同模量有限元法必定会有实际意义．
This paper applies the finite element method with different elastic modulus a in analyzing stress and shift of gravity dam. The fissure, contact and stability of dam may be calculated with given elastic modulus and Poisson's ratio in tension the finite element method with different elastic modulus will have practical applications in the mechanical analysis of rock, ice, ceramics and plastics.
