摘要
根据弹性波法的检测原理及特点,提出利用弹性波技术进行锚杆支护监测。该方法的原理:当锚杆头受到瞬态力激振后,引锚杆头质点振动,并以应力波的形状向锚杆底部传播。在锚杆、混凝土砂浆和围岩所组成的体系中,在锚杆端部发射一定频率的震动作为波源。具有监测周期短,费用低,并可实现三维空间连续、动态监测等特点。
According to the principle and characters of elastic wave technique, the paper analyzes the present conditions of bolting monitoring in mine roadway, and elastic wave technique are introduced to apply to bolting monitoring. The technique possesses not only short period and low cost, but also realize continuous and dynamic in 3D space.
