基于Cosserat连续体理论的重力坝深层抗滑稳定分析

为了在实践领域更加丰富大学生健康人格的实证研究,通过查阅有关资料、形容词法和头脑风暴法等方法编制了《大学生健康人格问卷》,并通过对2394名大学生进行调查,分析了大学生健康人格、心理症状与自我和谐的现状,探讨了三者之间的关系,为这三个领域的研究提供了一定的理论与实证支持.得出结论主要有:(1)自编的大学生健康人格问卷具有良好的信度、效度.(2)大学生健康人格与SCL-90总分及各维度呈显著负相关,与自我和谐总分.自我与经验的不和谐呈显著负相关,与自我灵活性呈显著正相关,与自我的刻板性无显著相关.(3)大学生健康人格水平对心理症状有一定的预测作用,自我和谐在健康人格和心理症状之间起部分中介作用.

Analysis of Deep Anti-sliding Stability of Gravity Dam Based on Cosserat Continuum Theory

User subroutine UEL of ABAQUS is used in secondary developments for an elastoplastic Drucker-Prager model based on the cosserat continuum theory. A uniaxial compression is performed, the result shows that this model can ensure well-posedness in strain localization. Strength reserve coefficient method is adopted to simulate strain localization for the foundation of gravity dam. Compared the result of the cosserat continuum theory to the classical continuum theory, it shows that: the result of the cosserat continuum theory is not sensitive to the mesh intensity, and strength reserve coefficient to FEM iteration unconverged has a substantial increase.
