| 摘 要： | 边坡开挖爆破必然造成边坡保留岩体的损伤。通过对边坡岩体取样岩芯的数量、位置以及岩芯声波速度的测试分析,认为光面爆破线装药密度对这种损伤作用有较大影响,同时岩体本身的缺陷(层理、片理、断层、节理等)也会增大这种影响作用,在选择边坡位置时应尽量选择岩体强度大,本身缺陷小的岩层。所得结果可为爆破设计和边坡稳定分析和维护提供参考。

| Abstract: | Smooth blasting of slope excavation would inevitably bring on damnification of slope remaining rock mass.Quantities,position and sonic wave velocity of core of slope remaining rock are measured and analyzed.The results show that linear charge density of smooth blasting for rock mass damnification has definite influence,and defect(bedding plane,schistosity,fault,joint,et al) of rock mass can also increase this influence,so strata of rock mass of more strength and smaller defect should be choosed when slope rock mass was selected.The results may be used for reference and provide a base for blasting design,stabilization analysis and maintenance of slope. |
