摘要
温福铁路琯头岭隧道在DK280+950～DK281+100段下穿同三高速公路琯头岭隧道,在将数值模拟结论作为施工方案制定依据的基础上,通过计算确定分部开挖几何形状及钻爆方案,并将监控量测数据作为施工过程控制的第一手资料,确保铁路隧道下穿公路隧道顺利完成。
Session DK280 ＋ 950 - DK281 ＋ 100 of Wenzhou-Fuzhou Railroad＇ s Guantouling tunnel passes underneath the highway tunnel, Taking the value simulation conclusion as the basis of construction plan and through computation, the geometric shape and the drill and blast plan of the partial excavation were determined. Moreover, monitoring and measurement data as the first-hand material of the construction control guarantees the smooth completion of the railway tunnel underneath passing the highway tunnel.
