摘要
缝管式钻孔多点位移计是一种新型的岩体内部位移量测仪器，具有结构简单、成本低廉、安装方便的优点。计算及实验结果表明：120mm长的缝管式锚头在钻孔中的锚固力满足位移计的使用要求。
The split-tuble multiple point borehole extensometer is a new type measuring instrument for the displacement within the rock body. Its advantage is that the instrument issimple with low cost and is easy for installation. The calculation and experiment results indicate that when a 120mm long split-tube anchor thrusted into a borehole,the anchorage forcemeets extensometer's working demands.
