摘要
软岩隧道施工过程中,超前地质预报与爆破设计对爆破效果影响更为突出,在隧道围岩变化的高频率和大幅度阶段,对控制隧道超欠挖至关重要。本文以十白高速公路花石沟隧道工程为背景,运用模糊层次分析法对隧道超前地质预报和爆破施工等因素进行分析,计算出各因素的权重,为同类型工程选择最优方案提供依据。
The advanced geological prediction and blasting design, which plays a key role in controlling over-break and under-break at the stage of high frequency and large amplitude in tunnel surrounding rock change, have a more prominent effect in the soft rock tunnel blasting construction. Within the context of the Hua- Shigou tunnel of Shi-Bai highway, we analyze these factors--advanced geological prediction, blasting construction by adopting fuzzy analytic hierarchy process. At last, we obtain the weight of each factor, which provides basis for the selection optimum scheme of the same type project.
