| 散射地震波CT技術(shù)在某隧道超前地質(zhì)預報中的應用(52卷) |
| 英文標題 |
| Application of scattering seismic wave CT (Computed Tomography ) technology to geological prediction for certain tunnel |
| 摘要 |
| 應用基于逆散射理論地震波CT成像技術(shù)，對某巖體破碎、裂隙發(fā)育隧道進行地質(zhì)預報，采用空間觀測系統(tǒng)和疊加能量最大化判定原理確定各段圍巖的最優(yōu)波速分布,有效地提高了速度分析精度和構(gòu)造定位精度;應用濾波技術(shù)有效地消除了面波和側(cè)向回波，保證了預報結(jié)果的真實可靠，成功解決破碎裂隙帶的地質(zhì)預報問題。 |
