根据主应力迹线指示的应力传递路径,构建出齿块锚固区的拉压杆模型,详细阐述了模型中关键节点及关键杆件所在位置,在此基础上提出基于拉压杆模型的齿块锚下局部受压承载力计算方法.与试验结果对比,本方法精度较高,可实现对齿块锚固区局部受压承载能力的合理预测. According to the stress transfer path indicated by the main stress trace, the tension and compression rod model of the anchorage zone of the tooth block is constructed, and the position of the key node and the key rod in the model is elaborated. Based on this, The method of calculating the compressive bearing capacity under anchor is compared with that of the test results.The method has high accuracy and can reasonably predict the local compressive loading capacity of the anchorage zone of the block.
