| Abstract: | Sandaogou Debris Flow Valley is located in Qifengcha Village,Liulimiao Town,Huairou District of Beijing. It is a prone and high-incidence area of debris flow geological disasters. There have been many debris flow geological disasters in history. This paper investigates the debris flow gully in Sandaogou by using high density electrical method,and finds out the thickness of loose source layer in the main gully of Sandaogou debris flow and the underground geological body of branch I. The reliability and validity of the exploration result of high density electrical method are proved by the validation of trough exploration,which provides an accurate basis for the prevention and treatment of the geological hazards in Sandaogou debris flow gully in the future. |
