摘要
三道沟泥石流沟流域位于北京市怀柔区琉璃庙镇崎峰茶村,是泥石流地质灾害的易发区和高发区,历史上曾发生过多次泥石流地质灾害。本文通过使用高密度电法对三道沟泥石流沟中的物源层进行勘测,查明了三道沟泥石流主沟及I支沟地下地质体中松散物源层的厚度,并通过槽探验证,证明了高密度电法勘探结果的可靠性与有效性,为今后该泥石流沟地质灾害的预防和治理提供了准确的依据。
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.
