摘要
隧道爆破施工所引起的环境振动可能对邻近建(构)筑物造成不利影响。对某新建公路隧道爆破进行监测,取垂直方向峰值最大波速为研究对象,运用萨道夫斯基公式对所测数据进行回归分析,结合爆破安全标准,对邻近输油管道的影响进行评价,并给出了合理的爆破减振建议。
Blasting is often needed in tunnel excavation,and it will affect the adjacent structures.The data of peak vertical wave velocities from the blasting vibration observation of a highway tunnel in construction are analyzed using Sadaovsky empirical formula.Based on the blasting vibration safety assessment standard adopted in China,the safety of the adjacent oil pipeline is evaluated,and the proper suggestions for reducing vibrations are presented.
