摘要
在我国的很多城市,浅埋隧道的高程范围内均存在较多的岩石地层。在该类环境中,通常以钻爆法修建隧道,爆破振动将对地表产生较大影响。以厦门机场路JC3标隧道工程为背景,通过现场监测,分析了振动的传播规律和对地表的影响,优化了爆破方案,较好地控制了振动对地表的影响。
There are lithostratigraphic environments in the elevation range of shallow tunnel in urban.In such environment,ground surface is influenced by blasting vibration from borehole blasting method,which threatens the building on the ground.Based on JC3 segment of Jichang Road tunnel engineering in Xiamen,the propagation of vibration and its influence for ground surface were analyzed by in situ monitoring,then the blasting plan was optimized,in which the influence of vibration to ground surface was controlled.
