利用自旋锚杆结构上的特点以及它独特作用原理,分析影响锚杆锚固力的因素,主要有土体粘聚力和内摩擦角。但是在应用过程中,发现土层的含水率对自旋锚杆的锚固力有较大的影响。通过现场试验和理论分析发现,土层含水率是通过影响土体粘聚力和内摩擦角来影响锚固力的,最后得出自旋锚杆的锚固力在一定范围内随着含水率的增加而减小,并且当土层的含水率达到一定的数值时,锚杆的锚固力就出现突然减小的现象,而且接近指数形式的减小。
Utilizing the characteristics of the structure of the spinodal anchor and its unique principle of action, the factors affecting the anchorage force of the anchor are analyzed, mainly including the cohesion of the soil and the internal friction angle. However, during the application process, it was found that the moisture content of the soil layer has a greater influence on the anchoring force of the spinning anchor rod. Through the field test and theoretical analysis, it is found that the soil moisture content affects the anchoring force by affecting the cohesion and internal friction angle of the soil, and finally, the anchoring force of the anchoring bolt increases within a certain range as the moisture content increases And decreases, and when the moisture content of the soil reaches a certain value, the anchoring force of the anchor suddenly decreases, and it approaches the decrease of the exponential form.
