从浅地表地球物理技术——走时速度层析成像、电阻率层析成像法、多道瞬态面波法三种方法的应用开始分析,进而探讨了地球物理勘探技术在岩土工程应用中面临反演不具有唯一性、现场条件违背反演的基本假设、勘探深度与分辨率、物理性质与工程性质存在连结等挑战,以期对地球物理勘探技术进一步的研究和改进,满足工程师的需求,更好、更广的应用在各类工程中。
The application of three methods of shallow ground surface geophysical technique - time-velocity tomography, resistivity tomography and multi-channel transient surface wave method are analyzed. Then it is discussed that geophysical prospecting technology is faced with geotechnical engineering application Inversion is not unique, the site conditions violate the basic assumption of inversion, exploration depth and resolution, physical and engineering nature of the existence of the link and other challenges, with a view to further exploration and improvement of geophysical exploration technology to meet the needs of engineers and more Good, wider application in all kinds of projects.
