| 摘 要： | 研究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 ,对试验数据进行了分析 .考虑到土体中裂纹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 ,得到了比较满意的效果

| Abstract: | The process of the model test is presented in great detail and the test data are sorted out and analyzed.As the developed cracks might have affected the stress and deformation in the retaining structure,the cracking mechanism is taken into account and a constitutive relation for cracked soils is built.An elastoplastic finite element computer program was developed in order to simulate the model test procedure.The calculated results agree well with the test data. |
