Five problems are discussed in this paper.

本文主要对以下五个问题进行了讨论:一、阐述了用电子计算机计算涂层电压分布的必要性。二、评述了国内外关于涂层电压分布计算的各种方法,并由此提出本论文的研究起点、内容和进行步骤。三、用国外文献所报导的显式差分格式结合我国所采用的涂层材料编制了计算程序,并从理论和试验两条途径对程序进行了检验。然后利用计算数据对国内目前采用的计算稳态电压分布的一些方法进行了评价。四、为了克服显式格式的不足,编制了预测一校正差分格式的计算程序。实际计算表明,计算时间比显格式快三十多倍。五、利用计算手段分析了线性和非线性涂层的特点,校核了现有防晕结构的参数,确定了一级和二级碳化硅涂层最佳参数的范围。

Recently the elasto-plastic FEM has been used in many projects to ana-lyze the destabilization process of concrete dams with their rock foundations containing soft interstitial materials. However the results show that it is difficult to assess the safty factor for designer's use by this method because no sharp turning can be found near the critical load on the Displacement-Load curve.In stead of the-elasto-plastic FEM, the elasto-visco-plastic FEM is suggested in this-paper to determine the safty factor in the stability analysis of concrete dams and their rock foundations. After a brief introduction of the elasto-visco-plastic theory the corresponding constitutive law is introduced into non-linear stress analysis. Some examples, are given with their results compared with those obtained by using elasto-plastic FEM. The comparison shows that by means of the method suggested by the authors it is easier to determine the safty factor because of the high sensi-bility of the displacement to a very small load increment above the critical point on the Displaqement-Load curve and more reasonable process of the development and linking-up of the plasticized zone can be obtained.

目前,许多工程都使用弹塑性有限元方法来分析基础中有软弱夹层的混凝土坝的失稳过程和安全度。然而计算结果表明:由于在用这种方法求出的荷载与位移的关系曲线上,临界荷载的位置往往难以确定,同时从应力成果也很难看出坝基中塑性区的发展以及塑化带逐步贯通的明确过程,因而难以为设计提供准确的安全系数。 本文建议用弹粘塑性有限元法求解抗滑稳定安全系数。在简述弹粘塑性有限元理论的基础上,本文把弹粘塑性本构关系作为非线性应力的计算手段引入坝体及其基础的抗滑稳定分析中,并把计算结果和弹塑性方法的结果进行了比较。比较表明:在用弹粘塑性方法求出的荷载与位移的关系曲线上,一旦超过临界荷载,对荷载的微小增量来说,位移增长幅度明显,因而能够为设计提供较精确的安全系数值,同时该法求出的塑性区及塑化带的发展贯通过程也更为合理。
