<*n style="font-family:宋体;mso-ascii-font-family:"Times New Roman"; mso-hansi-font-family:"Times New Roman"">锚索测力计在测力钢筒上均布着数支振弦式应变计，当荷载使钢筒产生轴向变形时，应变计与钢筒产生同步变形，变形使应变计的振弦产生应力变化，从而改变振弦 <*n style="font-family:宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family: "Times New Roman"">的振动频率。电磁线圈激振振弦并测量其振动频率，频率信号经电缆传输至读数装置，即可测出引起受力钢筒变形的应变量，代入标定系数可算出锚索测力计所感受 <*n style="font-family:宋体;mso-ascii-font-family:"Times New Roman";mso-hansi-font-family: "Times New Roman"">到的荷载值。<*n lang="EN-US">
