The 2D section of apparent resistivity contour lines is often used in the result interpretation of transient electromagnetic(TEM)。 However， the 3D image is more straight， more abundant information and more comprehensive interpretation compared to 2D image， and which will improve the TEM geological forecast interpretation accuracy。 Thus， the study of 3D imaging technique of TEM geological forecast becomes meaningful。 The paper put forward a 3D curved surface continuations imaging technique which base on the equivalent conductance plane method and introduce its principle in theory。 Through the engineering example， the TEM 3D curved surface continuation imaging technique characters and its application effect of tunnel geological forecast will be detailed analysis。 Finally， sum up some conclusions and laws， continuously improve the accuracy of TEM tunnel geological forecast。
