Abstract

The sloping ground operation of hydraulic structures associated with the collision of landslide phenomena and shear deformations. The work presents the results of research of influence of variability of physical and mechanical soil properties on stress-strain state of an earth-filled dam. To increase the precision of the calculations and reduce the complexity of work to determine the main criterion of safety of dams – factor of stability, made the automation of calculations. Automation is achieved by modeling the stress-strain state of the bulk soil structures by methods of analytic geometry, development of algorithm analysis-energy calculation the stability of the dam, implemented in the computer program "Ustoychivaya nasyp". Established multi-factor regression dependencies of the geometric parameters of the dam from soil strength characteristics allow for the design stage under-collection of the soils for specified parameters of the dams or to set the geometrical sizes of structures based on the mechanical properties of local soils.
