特大断面小净距隧道爆破开挖震动标准的研究
|
摘要
目前三车道公路隧道已建成不少,并积累了丰富的经验,然而对于单洞四车道特大断面隧道的修建在国内外并不多见。文章结合大帽山公路隧道的工程设计,应用有限元软件对大断面单洞四车道公路隧道支护结构强度及围岩稳定性进行数值模拟,并结合监控量测结果,确定合理的爆破震动速度标准,对日后类似工程具有积极的借鉴意义。
Up to now many three-lane highway tunnels have been built in China with abundant experiernce accumulated.Yet it is rare for large single tube highway tunnel with four traffic lanes.With Da Maoshan tunnel design as the background,numerical simulation has been carried out with FEM software for the large single tube highway tunnel with four traffic lanes to check support strength and the stability of surrounding rocks.On the basis of measured results of monitoring,this paper puts forward reasonsble blasting vibration creteria which will be helpfull for similar projects.
