摘要
SSP地震散射勘探技术是一种新的地震勘探方法。它利用地下介质的非均匀性产生的散射波对地质结构成像,分辨率高,图像直观,适合工程应用。将其应用到隧道塌方的地质病害诊断,查清了病害的地质原因及影响范围,取得了满意的效果,为隧道病害治理提供了可信依据。实际应用表明SSP技术适用于山区复杂地质条件的场地勘查。
Seismic scattering profile (SSP) is a new seismic survey technique, which utilizes the scattering wave generated by the heterogeneity of the underground mediums to image the geological structures. The images are of high resolution, intuitive and suitable for engineering applications. The application of SSP in tunnel collapse geological survey has achieved satisfactory results. The identification of the geological reasons and extent of the diseases are examined, which provide the reliable basis for the risk management in tunnel construction. The practical application shows that the SSP technique is suitable to survey in mountain areas or complex geological areas.
