To reduce the development of additional settlement
strip foundations of the existing building on the effect
of pressure transmitted to a ground base located near
the new slab foundation is considered the work of the
geotechnical barrier in various ground conditions. In
the first variant of soil, conditions (variant 1) made
geotechnical barrier structure in a homogeneous
thickness of the weak clay soil. In the second variant
of soil conditions (variant 2), a separating barrier is
performed in a two-layer base. The upper base layer
(carrying) is shown a weak water-saturated clay soil,
and the second (underlying) - low compressible soil
(sandy loam plastic). According to the results of the
calculations and modeling found that, the greatest
positive effect on the separating barrier structure
(geotechnical barrier) is achieved in the case when the
base is a two-layer. The lower part of the geotechnical
barrier must be recessed into the soil of low
compressibility. Additional settlement strip foundation
of the existing building in a uniform basis (variant 1)
in the absence of geotechnical barrier is approximately
8 cm. In the case of a two-layer base (variant 2), the
additional settlement strip foundation building is
reduced by 80-85% (6.6 cm) and will make about 1.4
cm
