摘要
爆破开挖会造成一定范围内围岩的破坏或松动，导致围岩承载能力下降。结合工程实践，利用声波探测技术对钻探岩芯和现场爆堆试块进行测试，并结合现场测试结果，确定破碎松动范围，互相验证。
Blasting excavation usually can destroy and slack adjonining rock in a certain range, resulting in a reduction in its supporting strength. In the light of certain engineering practice, the authors have tested drilling cores and test blocks from field muckpile by acoustic detection. According to the field measured results, the range in which rock is crushed and slacked is established. The results by the verification test show that the acoustic detection technique is reliable.
