The failure in predicting stability of the anchorage system will bring projects inestimable loss, so we must check if the anchor bars play the roles according previous design.
锚固系统稳定性预测一旦失误，往往给工程带来不可估量的损失，因而，需要检查它是否按设计预定的方式起作用。
The low strain longitudinal dynamic model of anchor bars-surrounding rock system under impulse force is established. The model is essential to nondestructive detection of anchorage system quality.
建立锚杆–围岩结构系统低应变纵向动力响应的数学力学模型，为研究锚杆结构系统的无损探伤原理及方法提供理论依据。
