摘要
针对洞口悬壁临河、出口接桥隧道,根据现场地形条件拟定进洞方案,通过环境保护、工期、经济分析,确定最终施工方案;重点介绍了此类地貌情况采取横洞进隧的施工技术措施,可为同类山岭地貌隧道进洞施工提供了一种实用环保的思路。
Aiming at those tunnels,whose entrances in the river or in hang edge,exports meeting bridge,it needs very detailed scheme into the hole in advance according to the topography condition.With the analysis of environment protection,construction period and economic factors,the eventually construction scheme could be made with in time.The paper mainly introduces construction measures of tunneling for such geography condition.It also provides practical reference and environmental guidance for similar projects.
