摘要
铁路隧道混凝土超耗受诸多因素影响,预留变形收敛是主要原因之一.本文通过大量的样本隧道,分别采用监控量测数据分析法和三维激光扫描仪实测法计算分析钻爆法施工隧道预留变形量和收敛值,揭示在正常施工条件下预留变形收敛对于混凝土超耗的定量关系,提出相应措施,为钻爆法施工隧道混凝土超耗控制提供借鉴.
Abstract
The excessive consumption of railway tunnel concrete is affected by many factors,and the reserved deformation convergence is one of the main reasons.Through a large number of sample tunnel,monitoring measuring data analysis and 3 d laser scanner measurement method calculation and analysis drilling blasting tunnel reserved deformation and convergence value,reveals the normal construction conditions reserved deformation convergence for concrete excessive quantitative relationship,put forward the corresponding measures,for drilling blasting tunnel concrete excessive consumption control.
