1) acoustic measuring boreholes arrangement
声波测孔
1.
Theoretical basis of the acoustic measuring boreholes arrangement for broken rock zone test in gently inclined thin layer weakness structure was studied through analyzing the mechanical characteristics of layered rock mass,the propagation rule of acoustic and distributions characteristics of plastic zone and slip zone in layered rock mass.
从层状岩体的力学特性、声波在层状岩体中的传播规律、围岩塑性区和剪裂区的分布特征3个方面,对缓倾薄层弱结构松动圈声波测试测孔布置的理论依据进行研究,提出声波测孔布置3项基本原则,即:巷道两帮测孔顺层布置;顶底板测孔垂直于岩层布置;塑性区和剪裂区较大部位加大声波测孔控制深度。
