| 摘 要： | 地震折射层析和高密度电法在隧道勘察中有着效率高、信息丰富、成本低、周期短、效果好等优点，因此得到了广泛的应用。对此，简介了折射层析成像和高密度电法的原理，采用高密度电阻率法与折射层析法对冰山谷沟隧道工程地质联合探测。利用折射波探测下方地质体中的波速特征，利用电阻率法探测地质体的裂隙发育及电阻率特征。综合两种方法进行风化带的分层，判断地质体的完整性及不良地质体的发育情况，并充分利用两种方法的优势，为后期隧道设计和施工提供地质信息和依据。

Application of Seismic Refraction Tomography and High Density Resistivity Method in Tunnel Exploration |
| |
| Abstract: | Seismic refraction tomography and high-density resistivity method, which have many advantages in tunnel exploration, such as high efficiency, abundant information, low cost, short cycle and good effect, are widely used. Herein the principle of the both methods were introduced, and the geological exploration was made by them on the tunnel engineering in ice valley gully in such manner that, by use of refractive wave, the wave velocity characteristics of underlying geological mass was explored and, by use of resistivity method, the characteristics of the fracture development and electrical resistivity thereof were explored. With these two methods, the weathered zone was layered to estimate the integrity of geological mass and the development situation of unfavorable geological bodies. Taking full advantage of these two methods may provide geological information and basis for the following tunnel design and construction. |
