Description
  • V článku je pospán program Plaxis, jako účinný nástroj por tvorbu výpočtových modelů seizmického buzení. Dynamickou analýzu lze v zásadě rozdělit do dvou základních typů úloh, kdy zdrojem dynamického zatížení je buď omezený jednobodový zdroj vibrací nebo zemětřesení. Problematika jednobodového zdroje je zpravidla modelována jako osově symetrická úloha, kde šíření vln probíhá analogicky jako v 3D systému. V takovém modelu dochází s rostoucí vzdáleností k rozptýlení energie vedoucí k utlumení vln (geometrické tlumení) Při modelování zemětřesení se dynamické zatížení zadává zpravidla na spodní část modelu, odkud se pak šíří směrem vzhůru. Tato problematika se řeší za podmínky rovinného přetvoření a v tomto případě je nutné definovat materiálové tlumení pomocí Rayleighových součinitelů. (cs)
  • Software system Plaxis which is possible to be used for creation of computing models of seismic generation will be specified in this article. Principles of dynamic analysis can be divided into two basic types; the source of dynamic load is either one-point source of vibrations or an earthquake. For an example the influence of quarry blasts (brown coal quarry in Northern Bohemia) was modelled with use of Plaxis system on stability and stress-deformation state of reverse slopes to define correlation with distances between the source of vibration and position of the slope. This problem was solved as an axially symmetric task. Reverse slopes are stable according to the model using dynamic load (coefficient of stability F=1.4). Parametric study enables us to evaluate influence of dynamic load depending on distances between the base of slope and the point of blast. In this case we documented that discussed distances do not have principal influence on the degree of slope stability but takes more significan
