爆破地震安全距离 谁帮我算一下啊急
爆破地震安全距离可按:R=(K/V)1/aQm
式中R:爆破地震安全距离,m;
Q:允许段炸药量,Kg;微差爆破或秒差爆破取最大一段装药量3.3kg;
V:地震安全速度cm/s,大坝取2.5cm/s;
m:药量指数,取1/3;
K,a:与爆破点地形、地质等条件有关的系数和衰减指数,根据夏河塔隧道地质、地形情况分析,K取200,a取1.8;
代入:R=(K/V)1/aQm=

爆破地震安全距离 R=(K/V)1/aQm
式中:R——爆破地震安全距离.
Q——炸药量(kg),齐发爆破取总炸药量,微秒差爆破取最大一段药量(5.85kg).
V地震安全速度(cm/s),取3cm/s.M——药量指数,取1/2.
K.,a——与爆破点地形、地质等条件有关的系数和衰减指数,K取
350,a取2.0.则R=24.4m

"Then they also lifted the San Francisco earthquake, found in the wood:" if you lost everything, they still have hope." The king said softly: "if a two children can find the courage and hope of words so an ordinary king can also be found." The king was Joseph king, he had saved card miro special.The......余下全文>>
