MODELING OF GEOTECHNICAL BARRIER IN WEAK CLAY SOILS ARRANGED TO PROTECT EXISTING BUILDINGS FROM IMPACT OF NEW CONSTRUCTION

abstract 1311707128 issue 131 pp. 1556 – 1570 29.09.2017 ru 295
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
