摘要
本文介绍了三峡工程茅坪溪土石坝施工过程中 ,沥青混凝土心墙两侧的块石爆破所诱发的振动对沥青混凝土心墙损伤影响的试验研究成果。通过各种工况下的心墙爆破振动测试及爆前爆后的声波及密度对比检测成果分析 ,并结合相关爆破振动安全标准的讨论 ,得到现有的施工工况下块石爆破所诱发的振动不会对沥青混凝土心墙产生损伤的结论。
The result of experimental study on the influence of boulder blasting vibration on the asphalt concrete core wall during construction of Maoping soil-rock filled dam is introduced in this paper. By analyzing the results of blast vibration monitoring, comparing measurement of sonic velocity and density on the core wall before and after boulder breaking, and combining with the discussion of safety standard of blast vibration, it is concluded that there is no damage of core wall under acting of vibration induced by boulder blast carried on construction site.
