山体滑坡对人类社会发展和经济建设产生巨大的危害,岩土剪应力减弱是引发山体滑坡的一个重要因素。针对山体滑坡的预防和监测,设计了一种现场测量岩土剪应力的装置,该装置包括十字板、扭矩传感器、步进电机、单片机硬件电路等;对实验装置的搭建和单片机硬件电路作了详细说明。该装置具有易携带、实时测量等优点,经过测试该系统具有良好的稳定性和测量精度,抗干扰能力强。
Landslides cause tremendous damage to the development of human society and economic construction. Weakened rock-soil shear stress is an important factor that causes landslides. Aiming at the prevention and monitoring of landslide, a device for on-site measurement of rock-soil shear stress is designed. The device includes cross-plate, torque sensor, stepping motor and SCM hardware circuit. The experimental setup and MCU hardware circuit Detailed description. The device is easy to carry, real-time measurement, etc., after testing the system has good stability and measurement accuracy, anti-interference ability.
