摘要
复杂的地质条件给解决隧道勘察中的工程问题造成了很大的困难,文章介绍了隧道勘察中常用的物探方法 ,并阐述了其在南山隧道勘察中的应用。多种物探方法的有机结合,准确的查明了隧道穿越区域的不良地质情况,各岩层风化层深度及分布范围,提供了纵波波速。综合物探技术可以极大地提高物探资料的解释精度和可靠度,这将对工程设计和施工提供非常有用的帮助信息。
The complicated geological conditions in the tunnel investigation bring difficulties to the solution of constructional problems. This paper generalizes the geophysical methods which are frequently used in the tunnel investigation, and expounds its application in Nan shah tunnel exploration. The organic combination of various geophysical conditions,which is used in the accurate identification of the unfavorable geological conditions of the tunnel through the area, the depth and distribution range of the rock strata, provides longitudinal wave velocity. Comprehensive geophysical survey can greatly improve the interpretation accuracy and reliability of geophysical data, which will provide useful information in engineering design and construction.
