Research on effective pit fencing solutions for the construction of a two-level parking lot of a multi-story building

A study on the effective placement of piles in retaining wall pit was carried out. comparison internal forces and horizontal displacements drawn among three variants their placements wall. The influence calculation results detailing soil excavation process during modeling using Plaxis 2D examined. Based research stress-strain state (STS) spatial setting problem, a to problem with flat drawn. Additionally, an analysis bending moments made.
 obtained results, information effectiveness different pile pit, as well convergence is presented. Also, values forces, displacements, elevation bottom between settings made. distribution presented.
 finite element model consists base structure. Modeling executed Hardening model, which following characteristics are used calculation: γ – specific weight its natural state; γsat water-saturated c cohesion; φ stress friction angle; ψ dilatancy E50 stiffness for primary loading; Eoed oedometer loading stiffness; Eur un-/reloading. made program complex.
 Today, most rational way design construction buildings structures underground parts significant. successful choice fencing not only ensures reliability but also allows building materials efficient way. In addition, method definition important factors when approaching similar problems, they affect accuracy degree labor-intensiveness, time spent calculation.
