摘要
为保证爆区临近建筑物的安全,对爆破振动效应必须实行严格控制。通过对建筑物群中基坑岩石松动爆破时爆破振动效应的实测,并用数学方法回归处理,求得该基坑岩石松动爆破条件下地震波的传播规律的经验公式。以此计算公式并根据《爆破安全规程》规定的安全允许爆破振动振速,求算出在保证安全前提下不同距离处的最大一次同段起爆药量。同时精心设计和施工,并采取有效措施降低爆破振动对临近建筑物的影响。
In order to ensure the safety of buildings near blasting zone, the effect of blasting vibration must be controlled strictly. Through measuring the blast vibration effect of loose blasting of foundation rock in buildings, this paper regressed the data by mathematic method and the empirical formula of transmission law of blasting vibration on this foundation rock loose blasting condition. The safe maximum explosive amount per delay in different distance was given according to this formula and vibration velocity permitted by Safety Standards of Blasting. The effect of blasting vibration to nearby buildings was reduced by well design and construction and effective measures.
