| 中文摘要: |
| 本文详细描述了大型室内粘性土柔性板桩模型试验从设计、准备、试验到数据采集的全过程，对试验数据进行了归纳、整理和分析。考虑到土体中裂缝的存在将会对板桩的受力和变形产生影响，引进了断裂力学的基本思想并推导了土体开裂后的本构关系，开发出弹塑性有限元程序对模型试验进行模拟分析，得到了比较满意的结果。 |
| 英文摘要: |
| In this paper, the process of the model test is presented in detail. The test data are sorted out and analyzed. The effect of crack mechanism is taken into account and a constitutive relation for cracked soil is established. An elastoplastic finite element program is developed in order to simulate the model test procedure. The calculated result is in good agreement with the test data. |
