| 摘 要： | 依据原地旋转模型和圆筒形模型,研究了自旋锚杆安装扭矩与锚固力的关系,指出两者均随锚叶直径的增大而增加。结合西安地铁2号线张家堡标段基坑工程,对自旋锚杆进行试验,试验结果表明:在不改变自旋锚杆自身参数情况下,安装扭矩与锚固长度呈线性关系,锚固力与锚固长度呈抛物线关系;当锚固长度一定时,锚固力和安装扭矩基本上呈线性关系。指出可以在工程应用中直接通过安装扭矩反映锚固力大小。

| Abstract: | Based on the in-situ rotation model and circle tubular model,the relations of installation torque and anchoring force of self-screwed bolt are researched,both of which increase as anchor blade dimension increase.Combining with the deep foundation engineering of Xi'an metro No.2 Line,experiments are carried out to self-screwed bolt,and the results show that when the parameters have no change,the installation torque and anchoring length have linear relationship,and the anchoring force and anchoring length hav... |
