摘要
通过应用折射层析成像法在乌鞘岭特长隧道中的测试,说明该方法对于横向速度变化不均一,过渡带速度渐变的地质情况具有分辨率高、图像直观、易于解释,适合对隧道围岩松动圈的测试。
Broken rock zone affect the stability of the under ground engineering. By discussing measuring the broken rock zone （BRZ） with refraction tomographic method in WUSHAO mountain tunnel, an effective measuring method of the BRZ was proposed. From the measured results we found the this method is with high distinguish rate, harsh image, and easy interpretative tomography.
