锚杆锚固质量动测法底端反射显现规律的实验研究

The laboratory study about the occurrence of bottom reflection rock of anchorage bolt bonding integrity by dynamical testing

运用应力波反射法,通过分段截取,在自制的模拟试件上进行了大量实验研究,找出了锚杆的底端反射 的出现与锚杆的自由端长度、锚固段长度、波长之间的关系.

By means of dynamic testing method, the sample models made by ourselves are studied in detail. We find out the relation between bottom reflection and the length of free section and anchor length and wave band.
