摘要
本文阐述了岩石松动层的声波测试技术的原理、仪器、方法及资料分析,运用声波法测试声波波速随测孔深度的变化,绘制波速与孔深的关系曲线,由此确定出岩石松动层的范围,并简述了现行测试方法存在的问题和改进方向,为岩石的稳定性评价及支护设计提供可靠的依据。
The paper expounded the principle,instrument,measures and data for the analysis of the sonic wave testing technique on the loosened layer of rock.After testing the change of wave speed with the depth of rock and protracting the relation curves showing the wave speed and the depth of the testing role by this technique,the loosened layer of rock will be identified,and the problem and ameliorating direction of the testing technique are recited,which will provide a reliable basis for the evaluation of rock stability and support design.
