摘要
阐述了CT成像及其反演算法的基本原理 ,结合齐峦山隧道勘探的实例可以看出SIRT反演算法得出的成像剖面精度很高 ,从而使其在判断岩溶、裂隙及岩石破碎发育带方面具有独特的优势。
The CT imagining technique and the basic principle of converse deduction method are expounded. Through the case of a tunnel's exploration, it shows that the imagining profile produced by SIRT method has very highly accuracy, which has the particular advantage of judgment for the grown zone of karst, crack and rock crush.
