摘要
邓肯模型关于轴向应变εα与侧向应变εγ成双曲线关系的假设目前已普遍受到怀疑．为此，笔者在静力学模型材料试验中找到了与实验所得的泊松比变化规律吻合很好的拟合曲线关系．用这样的拟合曲线关系进行土石坝坝体稳定分析，求得的应力水平等值线图应是较合理的．笔者还进行了一些对比研究，为探索坝体稳定分析时泊松比的取值提供了一些建议．
The hypothesis in Duncan Model, the relationship between axial strain and lateral strain is hyperbolic, has been generally doubted. From the analysis of the result of Statical Model Test, we have found an approximation curve relationship which tallies with the law of Poisson's ratio from tests. Using such a relationship in stability analysis,reasonable stress isograms can be obtained. Some contrast researches are also made, and some suggestions on getting Poisson's ratio in the stability analysis of dam are offered.
