摘要: There are still many problems although new concept highway design has been practiced for many years in our country .The most prominent is the lack of creative generation method guide to highway de‐sign ,and this is not a problem which can be easily solved in hard science .Based on this ,extension theory and method have been introduced in the paper ,with the method of new concept slope design taken as breakthrough point ,and the feasibility and method of highway slope creative design analyzed by means of extension thinking mode .Example analysis shows that applying extension thinking mode to new concept slope design is appropriate and feasible ,it can be used for reference for relevant scholars and technicians .
