This paper focuses on dangerous rock body of Yonglan expressway. The author studies causes of thedangerous rock disasters of highway slope and puts forward suggestions for disaster prevention by means of fieldinvestigation and theoretieal analysis. lt also identilfies the disaster-causing environment of dangerous rock masson the north side of Heyetang viaduet, and analyzes topography , meteorology and hydrology , lithology , geologieal structure, hydrogeologieal conditions, ete; it also finds out the reasons for disasters by field survey: thestudy shows that the conditions of formation lithology and geologieal structures are main factors affecting the de.velopment of dangerous rock mass; disaster prevention measures against the dangerous rock mass of “ bolt an-choring + drainage + linked network prolection" are put forward through mechanies caleulations. The re-seareh provides a basis for disaster prevenlion of highway engineering.
