【摘要】 受地形地质条件限制,百色水利枢纽工程的备用料场选择在地下厂房附近。为了解备用料场开挖爆破施工对正在建设中的地下建筑物的安全是否产生不利影响,并有效控制和减少这些不利影响,进行了现场爆破试验研究。结果表明:只要严格控制单响药量不超过300kg,并有良好的临空面,就不会对地下建筑物产生不利影响。更多还原

【Abstract】 From geologic and geomorphic limits, the jury stocking yard of Baise Haydro-junction was selected at near underground plant, and its extra blasting to the underground structures during construction would create unfavorable effect. How to reduce and control this effect, field test and analytic argument were conducted. The field test results showed that the blasting would not cause disadvantagcous effect, as long as the powder quantity of blasting at a time isn’t over 300 kg.更多还原
