Soil deformation in landslide and the treatment are important in the landslide control construction. Taking a landslide hazards control project in Dongyuan of Lanxi City as an example, this paper introduces a series of measures adopted for the local instability occurred in the construction process, including the analysis on the recent soil deformation characteristics and the reasons, emergency rescue measures, monitoring of emergency evacuation effects and subsequent construction plans, etc. These measures have achieved good results and provided reference for the similar construction.
