摘要
根据沪蓉西高速公路ZK107+157—268段路堑边坡和ZK107+730—816段路堑边坡爆破工程现场爆破振动测试得到的数据,经数学回归分析处理,得到该爆破工程的爆破振动传播经验公式,由所得到的公式计算出在不同的爆破药量下不同距离处建筑物的振动速度,再参照不同类型建筑物在爆破时所允许的安全振动速度标准,对爆区周围民用建筑的安全进行了评价,同时给出了爆破振动安全允许距离。
The blasting vibration data at ZK107 ＋ 157--268 road slope and ZK107 ＋730--816 road slope of Hurongxi expressway was observed, analyzed and processed, and the decay experience formula of blasting earthquake wave was obtained. The vibration velocity of buildings at different distance was calculated by the decay experience formula,with reference to the safety level of blasting vibration of buildings in our country,and the safety of buildings near the blasting area was evaluated. The safety distance of blasting vibration for different buildings was given out.
