In the paper possibilities of constructing industrial heavy structures near slopes are described. The influence of tectonics, seismicity, a relief, deposit rocks thicknesses, their physical properties of geotechnical engineering feature are analyzed. The law of marls durability change is established. Positions of the most probable surfaces of sliding in cracked monoclonal deposit thickness are shown. The estimation of stability of the loaded slopes is made. Some recommendations for maintenance of structure stability are given.
