Indian geotechnical journalSummary: The naturally stable slope of Bekhme Residential Complex had been cut to eight steps. These steps are about 30–40 m in runs, with a rise of about 5–7 m. On these steps, the residential complex was built, supported by retaining walls. The construction operations began, and many failures occur after a few months. Three reasons for failures were pointed: weakness of slope materials, the effects of groundwater, and unconsidered present design of slope pruning. The slope materials are representative of clastic rocks, i.e., shale, mudstone, rock debris, and soil. The groundwater is 2 to 3 m high from the base of the retaining walls. A simple cutting-style slope has been used that has made large steps up to 5 to 7 m. The fieldwork comprises photo-documentation of successive failures, assessing the primary design and the investigation of slope materials, monitoring slope failures and demonstrating groundwater and tension cracks. Physical characteristics include grain size distribution and index properties to classify the slope materials that were carried out in the laboratory. For four types of remolded slope material, the peak and residual shear strength were obtained. The greater plasticity index of the lowest shear strength material shows the ability to compact and demonstrate extra shear strength. The greater plasticity index of the less shear strength material is capable of compacting and exhibits additional shear strength. Merely, among 17 sites, five sites have a good safety factor over 1.4. According to the entire information, which is concerned with maintaining the original steepness and cutting in stable mode, in order to save souls and buildings, the study seeks to maintain and repair the horrible situation of the residential complex.
