| 摘 要： | 基于应力波反射法,通过不同围岩级别和锚固介质中锚杆的瞬态动力响应实验研究,对锚杆的加速度响应曲线的波形特征进行分析.结果表明,随着龄期的增长,固端反射信号非常强烈,而底端反射信号越来越微弱,甚至很难识别;围岩和锚杆介质均匀密实的锚杆其信号相对平缓一些.

| Abstract: | Based on the stress wave reflection method,an experiment was conducted to study the transient dynamic response of bolts in different surrounding rocks and anchorage media and analyze the waveform characteristic of acceleration response curves for bolts.The results show that the reflection signal of fixed end is very strong and the reflection signal of bottom is increasingly weak with curing,and that the signal of bolt in uniform surrounding rock and anchorage medium is gentler. |
