| 摘 要： | 通过块体集上限分析方法，研究锚板的抗拔承载力和破坏面特性，并将分析结果与Das1]以及Rowe2]的锚板模型试验结果进行详细对比，验证块体集上限法的有效性。分析斜坡地形条件下锚板抗拔承载特性，并与Khing等3]的条形锚板抗拔承载力试验以及Rao和Prasad4]的圆形锚板抗拔承载力试验进行详细对比，分析斜坡地形条件下锚板模型试验中采用拉杆加载的方式对于试验结果的影响。分析结果表明，斜坡地形条件下拉杆的存在对于锚板抗拔承载力影响较大，模型试验应优先采用Trapdoor模型。

| Abstract: | The block set mechanism was used to analyze the characters of pull-out capacity and failure surface of anchor plates. An application to upper bound analysis of vertically loaded strip anchors on horizontal ground surface is given first to illustrate the utility and effectiveness of the proposed method，and include detailed comparisons with model test results of Das1] and Rowe2]. Then analyses of anchor plates were given with emphasis on consideration of sloped ground. Comparisons between theoretical predictions of block set mechanism and model test results of Khing et al3] and Rao and Prasad4] are presented. The results show that the steel rod which adopted in model test as a loading device has a significant effect on pull-out capacity of anchor plates. So the Trapdoor model should be given priority in the model test of anchor plate which the sloped ground was taken into consideration. |
