An designed monitoring system was used in this paper to monitor the typical landslide in Zhenjiang area. The process of landslide about accumulative displacement, deformation rate and acceleration has been analyzed. The process of landslide was divided into three phases including an initial deformation phase, a uniform deformation phase and an accelerated deformation phase. The numerical simulation results show that the destructive model of landslide is creeping-tension cracking. Special topography provides a good free face for landslide. Moreover, under the influence of water cycles, the mechanical strength of the silty clay decreases affecting the slope stability. After rainfall infiltration, the transient saturation region is formed, resulting in the decreasing of effective stress, and producing the hydrostatic pressure and dynamic pressure which point to the free face. Therefore, the sliding force increases and the resistance force decreases.

The IPL project No 181 titled "Study of slow moving landslide Umka near Belgrade" started in November 2012. The study area is located on the right bank of Sava River, 25 km south west of Belgrade, Serbia. The basic objective of the Project was to enable the analysis, correlation and synthesis of data obtained from various phases of investigation of Umka landslide after 35 years of research. Apart from this, the analysis of data from monitoring conducted during certain phases of research was compared with data from automated GNSS monitoring over the last six years, although during numerous investigations various research methods were used for research and monitoring. The project was focused on: analysis of previous detail site investigations and field instrumentation from 1990-2005, analysis of aerial photos and orthophoto images from 1957-2010, analysis of automated GNSS monitoring results from 2010 to end of the Project and analysis of precipitation and levels of the Sava River. Project beneficiaries are local community and local and regional authorities. In this paper we will present results of the proposed project targets performed by Project participants.
