摘要
针对温州绕城高速公路北线工程5座大跨度隧道的施工,结合科研,进行连拱隧道的施工力学分析、分离式隧道横洞开挖力学效应分析、隧道岩爆发生机理和处理措施研究、连拱隧道爆破振动效应分析研究。采用较为先进的施工技术并获得预期效果,经济和社会效益显著。
Aiming at construction of five tunnels in Northern Project of Ring Expressway around Wenzhou and in combination with scientific research,this paper carries out mechanical analysis for construction of bi-arch tunnels,mechanical effect analysis for excavation of cross caves in tunnels,study on mechanism of tunnel rock explosion and treatment measures,analysis and investigation for blasting vibration effect of bi-arch tunnels.The more advanced construction techniques are incorporated and the anticipated effects are obtained with outstanding economic and social benefits.
