Abstract Abstract：Research purposes：Two serious landslide danger appeared in the section of the subgrade of the fifth tender in the Kunming south connecting highway engineering, in the upcoming delivery before acceptance. One of them has been completely slump，another has been in critical state before sliding collapse. Through on-site investigation and analysis of the engineering case and remediation treatment, try to find a way to predict early engineering landslide and to provide countermeasures in order to reduce or even avoid engineering landslide disasters，to provide reference for dealing with the similar problems of the slope engineering in the highway, railway, subway, reservoir dam and other projects in the future.
Research conclusions：(1) The nature and status of the two existing landslides are very different. Among them，one in K 23+475～550 is shallow bedding rock landslide in a state of sliding down completely，which has been basically stable；another in K 23+680～800 is deep towed soil landslide，in the stage of the creeping deformation into the sliding down，and its state is very unstable. (2) By using integrated geological analysis method，it has been analysed and predicted that the slope in K 23+550～680 is potential shallow bedding rock landslide，and a great possibility slumping. (3) According to the natures characteristics of their own，different regulation scheme are put forward，which in turn are respectively: thoroughly remove, pre-reinforcement, emergency anti-sliding and permanent against sliding. (4) The method of integrated geological analysis which is put forward in this paper，will provide a reference for predicting disaster, emergency rescue, permanent remediation of the similar slope engineering.
