摘　　要：万家寨引黄工程总干线一、二级泵站变电站及控制楼由水电六局进行地基场地平整,爆破采用有自由面的光面爆破。为了评价爆破作业对岩体的破坏影响程度,太原理工大学受承包商和监理的委托,对原岩体进行爆破前后的岩体声波速度检测试验,通过试验以检测该部位的岩体是否有破坏及破坏程度的大小。本文以二级泵站为例说明检测的方法及过程。The site leveling project of substation and control building of the pumpi ng station NO.1and NO.2of the general main line,Wanjiazhai YRDP(Yellow River Diversion Project)was done by blasting.In order to check the impact of the blasting above mention ed to the rock foundation,the longit udinal wave speed of the rock mass in t he foundation was tested before and after the blasting,The process of the te st,in the pumping station NO.2which is taken sa a example,is described in th is paper.
