Abstract

Abstract. Purpose.  In practice, the design and operation is necessary to assess the possibility of deformation structures located  on the grounds, which are possible uneven rainfall and subsidence. Only with reliable and detailed definition of the stress-strain state  of  structures  designs  in  conjunction  with  the  soil  mass  in  the  simulation  can  be  reasonably  applied  to  the  FEM  practice.  Methodology.  The present level of computer hardware and software allows you to perform more accurate calculations of the stress  state  of  fairly  complex  systems.  For  some  programs  possible  solution not  only  linear  but  also nonlinear problems.  This  provid es  accounting  features  of  deformation  of  different  materials:  concrete,  steel,  soil,  etc.  To  take  into  account  the  work  of  the  soil  developed several models that take into account the transition of soil in a plastic state, the elastic deformation and other  models. A  comparison should be of adequate models and testing them to solve practical problems. Currently, the most widely used several large  programs, developed in theUnited States,Western Europe,UkraineandRussia. InUkraine, widespread program of Lira-Windows,  Monomakh, SCAD -  Office, which focused mainly on estimates of construction projects. In the world a large amount of problems  solved with the programs ANSYS, PLAXIS, SolidWorks, LS-DYNA, Midas GTS NX and others.  Originality.  Calculations using  PLAXIS  program  allowed  an  analysis  of  the  stress-strain  state  of  the  soil  mass  and  stability  of  retaining  walls:  I  option  -  the  prototype, angular retaining wall:  II option  -  retaining wall of a special type. At the same ground-based (the geometry of the layers  and the physical and mechanical properties), loads and boundary conditions, load obvious presence of the II option included in   the  work of the whole array of ground and uniform redistribution of stresses on the front and the base plate (for common voltage)  is  uniformly  total  deformation  structures  and  ground  a  base,  which  in  turn  provides  greater  stability  of  the  retaining  wall  (mot ion  picture on the total). Practical value. The validity of the theoretical prediction of behavior of engineering structures, interacting with non-uniformly deformed-basics can not be obtained on the basis of the regulatory framework. This gap can be filled in the simulation  system "foundation - engineering facility" with the help of modern calculation FEM programs.
