摘要
文章以蒙华重载铁路重难点工程—黄柏岭隧道、洛河大桥桥隧相接、桥隧交叉施工为背景,制订了桥隧交叉施工方案,包括洞外防护方案和洞内控制爆破开挖方案,对主要施工方法和技术保证措施进行分析阐述,以期有效保障两个重点控制性工程的稳步推进和桥梁隧道的施工质量。
Taking the key and difficult projects of Menghua heavy-haul railway--bridge-tunnel connection and bridgetunnel crossing construction of Huangbailing tunnel and Luohe bridge as the background, this paper formulates the bridge-tunnel crossing construction scheme, including the protection scheme outside the tunnel and the controlled blasting excavation scheme inside the tunnel. The main construction methods and technical guarantee measures are analyzed and expounded in order to effectively guarantee the steady progress of the two key control projects and the construction quality of the bridge and tunnel.
