在抵抗岩体冲击、剪切和能量吸收等诸多方面,具有负泊松比效应的材料比传统意义下的泊松比材料表现出更为优异的性能。因此,针对普通锚索无法抵抗矿山滑坡大变形灾害而发生锚索拉断等问题,研发了具有负泊松比效应的恒阻大变形监测锚索,该缆索集监测-预警-控制功能于一体,具有高恒阻、大变形、超强吸能等特性,已经成功应用于矿山滑坡灾害监控领域。通过现场静力拉拔试验,对3种不同规格恒阻大变形缆索的轴向变形、径向变形和恒阻力进行连续测量,试验结果证明3种不同规格的恒阻大变形监测缆索均具有恒阻吸能特性,当恒阻值分别达到200、500和850 kN时,最大变形量可达2000 mm,填补了国内外大变形缆索的研究空白。

Materials with negative Poisson′s ratio effect including energy absorption than the traditional sense of the Pois-son ratio of the material exhibits a more excellent performance in rock shock resistance,shear and many other aspects than the material with the traditional sense of the Poisson ratio. Therefore,in view of the issues that ordinary cable cannot resist the large deformation of soft rock and rock slope anchor breaking,a novel cable with large elongation and constant resistance and also with negative Poisson′s ratio effect has been researched and developed. The cable integrates the functions of monitoring-warn-ing-control,with characteristics of high constant resistance,large deformation,super energy-absorbing,and successfully applied to the mine disaster control field. The axial deformation,radial deformation and constant resistance of large deformation cable with three different specifications of constant resistance were continuously measured. The experimental results show that all these cables have properties of constant resistance and energy absorption. The maximum deformation reaches 2000 mm during the constant resistance up to 200 kN,500 kN and 200 kN. This research fills the gaps in research of large deformation cable at home and abroad.
