地震CT技术在白泥井隧道病害探测中的应用

Application of Seismic CT Technology in Disease Detection of Bainijing Tunnel

摘要: 地震CT技术可将地质体内部结构进行直观的显示，具有分辨率高、可靠性好、图像直观等特点，因此广泛应用于工程地质勘查和病害诊断中。本文首先对地震CT的基本原理进行介绍，然后对白泥井隧道施工中遇到的病害情况进行描述，最后利用地震CT技术对白泥井隧道进行探测，分析其造成隧道病害的原因。通过与隧址区地质环境进行验证，证明地震CT技术探测结果的准确性，同时结合分析结果，提出相应的处置建议方案，为隧道施工建设提供依据。

Abstract: The seismic CT technology can intuitively display the internal structure of the geology, and it has high resolution, reliability, and intuitive images. So it is therefore widely used in engineering geo-logical exploration and disease diagnosis. This paper first introduces the basic principles of seismic CT, then describes the disease conditions encountered in construction of Bainijing tunnel, and finally uses the seismic CT technology to detect Bainijing tunnel and analyzes the causes of tunnel diseases. Then the geological environment of the area is verified to prove the accuracy of the de-tection results. Combined with the analysis results, a corresponding disposal proposal is proposed to provide the basis for construction of the tunnel.
