近年来我国水利水电岩体预应力锚固技术有了较大发展,锚固荷载已超过6000kN,为了准确评价锚固效果,满足施工监测和长期观测的需要,改变预应力锚固监测设备精度差,受外荷环境干扰大(如:受电磁场干扰、温度湿度变化剧烈、爆破震动、坍落岩石的冲击),适应偏载的情况下能够运行正常,特研制了LC～3000、LC-6000型轮辐式测力传感器,并应用于锚固工程获得满意的成果,本文主要介绍LC-6000型轮辐式测力传感器的研制与应用。
In recent years, China’s hydroelectric power rock bolting prestressed anchorage technology has been greatly developed, the anchorage load has exceeded 6000kN, in order to accurately assess the anchoring effect, to meet the needs of construction monitoring and long-term observation, changing the prestressed anchoring monitoring equipment accuracy is poor, Environmental interference (such as: the electromagnetic interference, temperature and humidity changes violently, blasting vibration, the impact of slump rock), to adapt to the partial load of the case can run normally, specially developed LC ~ 3000, LC-6000 type spoke force Sensor, and applied to the anchor project to obtain satisfactory results. This paper mainly introduces the development and application of the LC-6000 spoke-type force sensor.
