the front side bulk soils make up the foundation of
building a solid cover of capacity from 2.9 to 4.0
m, then the left and right sides of the building ca-
pacity in the range of from 0.5 to 8.0 m.
According to the results of sensing reconstruc-
tion of the basement of the madrassah was con-
duct.
Groundwater in the study period (December,
1999) opened at a depth of 5,4-8,8 m from the
ground, depending on the terrain that at an altitude
423,5-424,5 m.
According to long-term regime observations,
the maximum level of groundwater is observed in
August-September,
and the minimum - in Janu-
ary-March. Opened groundwater level is close to
the minimum level.
The amplitude of the fluctuations in the level
of the multitude of years is 2.0 meters. The esti-
mated maximum groundwater can be expected at
absolute elevations of 426.5.
Mineralization groundwater characterized by
containing the solid residue equal soluble salts
766.48 mg/
l. of sulfate ions at a content of 307.72
mg/L, chlorine ion 70 mg/
l. according to [7] un-
derground water estimated to be slightly aggres-
sive to concrete permeability normal portland ce-
ment.
Soils contain a base composition water-soluble
salt. According to chemical analysis of the aque-
ous extract from the solid residue soil
quantity of
water-soluble salts in the dry soil is from 1772 to
9687 mg/kg, the content of sulfate ions from 852
to 6485 mg/kg, and the chloride ion of 87 to 96
mg/kg.
According to [7] primers forming the portion,
the degree of exposure to the aggressive concrete
and reinforced concrete structures are evaluated as
portland cement are strongly aggressive. Corro-
sion activity soil activity to steel (cathode current
density, A/m

is estimated as the average (cathode
current density exceeds 0.05 A/m

), to aluminum
and lead-sheathed cables, it is estimated as high
(humus content exceeds 4000 mg/kg [4].
Within the area of research, to scout out a
depth of 9.0m, revealed two layers.
The first layer is a bulk ground-loam broken
structures
incorporating residential, construction
waste (organic residues, brick rubble, pebbles and
so on up to 20%). Bulk soil of heterogeneous
composition, density and sometimes unconsoli-
dated. Soils subsidence at P = 0.3 MPa.
Bulk soils occur in the upper part of the section
(Figure 4). Power bulk soil ranges from 1.9 to
8,0m. from the surface of the earth, dry soil den-
sity varies from 1.18 to 1.53 t / m

Sagging properties of soils characterized by
values comparative subsoil at P = 0.3 MPa from
0.008 to 0.068, while the natural pressure of 0.001
to 0.024.
The initial pressure drawdown ranges from
0.04 to over 0.30 MPa.
The initial and final
subsidence of moisture
and humidity in full water saturated: Wsl = 0,204;
Weq = 0,241; Wsat = 0,315.
Mechanical properties of soils are character-
ized by the values of the specific adhesion, meas-
uring, Misia from 4.0 to 13.0 kPa and the internal
friction angle of 27° to 28°.
Deformation properties of soils by laboratory
data are characterized by the values of someone
compressive module of total deformation of 2.2 to
15.8 MPa, standard value of 7.1 MPa. When the
total value of the saturated soil deformation varies
from 1.7 to 7.4 MPa, the standard value of 3.5
MPa.
The second layer is represented by loess-like
loams, light brown, macroporous, wet and water-
saturated.
Loam lumpy in places, mainly subsi-
dence at P = 0.3 MPa.
Soils overlie the second layer under the bulk
soils at a depth of 1,9-6,2 m, sometimes deeper.

ies from 1.48 to 1.66 t/m

Sagging properties of soils characterized by
