| 中文摘要: |
| 本文针对由夹心板、组合板、复合材料迭层板等复合结构及厚壁结构构成的地下结构，在动载救大产生大挠度变形时，提出了一种双有限厚条法．这种方法特介质及衬砌均看作厚壁结构，沿母线方向取有限厚条进行离散，这样便可以将三线问题化为一维问题进行数值计算，大大减少了计算工作量，且其精度与通常的有限条法相当． |
| 英文摘要: |
| This paper presents a finite thick double-strip method for analyzing geometrical nonlinear dynamic response of underground construction which is made by sandwich plate,composite material,laminated plates and thick-wall structures. In this method the soil medium and lining are both considered to be thick-wall structures,and using the finite thick strip technology the calculaion of the three-dimensional underground structures can be simplyfied to the one-dimensional numerical problem.The memory requirments and the computational efforts of this calculation are reduced considerably.Comparing with the general finite strip method,the precision of the method proposed in the paper is satisfactory. |
