Interaction of engineering protective structures with the soil base in densely built-up territory

The article analyzes the operation of "engineering protective structures-soil massif" system in zone influence surrounding buildings presence complex engineering and geological conditions. Simulation task setting up a deep pit under protection with multi-tiered retaining wall was carried out. mutual development near new construction, depending on distance between them, revealed. optimal existing building construction determined.
 It has been established that taking into account when constructing significantly changes nature stress-deformation state soil base enclosure structures, increasing movement supporting structures by 12-72% to house.
 found bending moments structure fence undergo quantitative qualitative is reduced. Thus, values piles increase 25% reduced from 20m 10m, 46% 10m 5m.
 shown reducing leads occurrence additional settlements foundation building. vertical deformations house located at 5 m 35%, compared 20 m, which explained falling formation slope sliding surface.
 most rational location case depth equal face structure, since does not fall construction.
