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Das[1]以及Rowe[2]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Prasad[4]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。
Through the method of upper limit analysis of block sets, the pull-out bearing capacity and failure surface characteristics of anchor plate are studied. The results of the analysis are in detail compared with the anchor plate test results of Das [1] and Rowe [2] The validity of the law. The bearing capacity of anchor plate under slope topography is analyzed and compared with the pullout test of strip anchor plate in Khing et al. [3] and the pullout test of circular anchor plate in Rao and Prasad [4] The influence of loading method of tie rod on the test results in the anchor plate model test under slope topography was analyzed. The analysis results show that the existence of the tie rod has a great influence on the pull-out bearing capacity of the anchor plate under the condition of slope topography, and the Trapdoor model should be prioritized in the model test.
