Anchor rod for self-testing shearing force based on force transducer
The invention discloses an anchor rod for self-testing shearing force based on a force transducer. The anchor rod comprises an anchor rod front end, an anchor rod middle end and the force transducer. The anchor rod front end comprises a bolt, a rubber plug, a base plate, a stop-grouting plug, a displayer and an outer end computer. A long rectangular groove is formed in the surface of an anchor rod body in the middle end of the anchor rod in the axial direction, and three short rectangular grooves with different depths are formed in the direction perpendicular to the axial direction at equal intervals. The force measurement sensor comprises an optical fiber sensor and an attitude sensor. According to the method, the corresponding force measuring sensor is arranged in each groove, and the magnitude of the shearing force borne by the anchor rod in actual use is detected and calculated through the small strain of the force measuring sensors. The device has the advantages of being simple in structure, high in functional practicability and the like, shearing force can be monitored in real time, the accuracy and precision of data are improved, and the device has an important guiding effect on shearing resistance research and support design of the anchor rod in a multi-joint and fissure medium or under the action conditions of large burial depth and high ground stress.
本发明公开了一种基于测力传感器自测剪力的锚杆，包括锚杆前端、锚杆中端和测力传感器三个部分。锚杆前端包括螺栓、橡胶塞、垫板、止浆塞、显示器和外端电脑。锚杆中端在锚杆杆体表面沿轴向方向布置一条长矩形凹槽，沿垂直于轴向方向等距布置三条不同深度的短矩形凹槽。测力传感器包括光纤传感器和姿态传感器。本方法通过在每个凹槽处布置对应测力传感器，利用测力传感器的微小应变检测计算锚杆在实际使用中所受剪力的大小。该装置具有结构简单、功能实用性强等优势，可以进行剪切力实时监测，提高数据的准确性和精确度，对处于多节理、裂隙的介质中或者大埋深、高地应力作用条件下锚杆的抗剪性能研究以及支护设计具有重要的指导作用。
