SIMULATION OF THE PROCESS OF DEFORMATION OF BROWN PILES FOR IGE

Abstract

Designing reliable and ekonomicznych modern construction projects, which are themselves large-scale structures, is relevant, so the proper use of soil mechanics is especially important when design and construction. Soil mechanics is the mechanics of natural dispersed (finely crushed ) bodies, includes both the laws of theoretical mechanics (mechanics of solid brand neszhimaemoi bodies) and the patterns of structural mechanics (the laws of prognosti, plasticity). The success of foundation engineering as a whole is tied to its scientific base - soil mechanics.

The boundary stress state of the soil at a given point of otvechaet such stress condition, when a slight additional effect of narushaet the existing balance and makes the ground in an unstable condition in the soil mass occur of the sliding surface, discontinuities, subsidence and broken strength between its particles and aggregates. Such a stress state of soils must be considered as invalid if construction on their facilities. Therefore, for engineering practice, it is very important to be able to estimate the maximum possible loading on the soil in which it will still be in equilibrium, ie, will lose strength and stability.

In connection with increase in volumes use of bored piles is a necessity of developments of modern predictive methods for the determination of their carrying capacity with the involvement of computers as the main challenge in the design of structures is an engineering assessment of the load-bearing capacity of soil based ... In working on numerical BEM modeled the process of deformation of the bored SAI. Questions of strength, bearing capacity , stability of soils is a task of the General theory of limit equilibrium, the beginning of which was laid by the works of M. Coulomb, L. Prantl.
