摘要
Engineering geophysical exploration has been playing an important role in foundational site investigation as an important means of engineering investigations by virtue of its high efficient,non-destructive,high-density,low-cost characteristics.Single geophysical method will be subject to geological and geophysical constraints,so that the geophysical accuracy can be affected.Integrated geophysical methods can improve the quality of the analysis of the geophysical results and the accuracy of the geological interpretation to meet the requirements of the engineering investigation.In this article,with the particular engineering cases,three different types of geophysical methods and techniques including two-dimension resistivity,shallow seismic reflection and geological radar are taken as examples used in engineering foundation exploration.Because three different types of geophysical methods reflect different physical properties on engineering fundamentals,the accuracy of the comprehensive exploration results has been greatly improved,and made a good exploration results by a comparison and comprehensive analysis between the geophysical results and geological data,and the results are verified by drilling.The article also introduced the principle,techniques and data interpretation of the used geophysical methods,which should be noticed in practice.
