Abstract

Purpose. The analysis of opportunities of use of strengthening of sloping ground for planting and creating of landscape compositions, determination of advantage of their use in the existing environment of the city and requirements to retaining wall structural design for effective planting. Methodology. Computer modeling applying soil FE of LIRA SAPR 2014 software. Results. In case of insufficient bearing capacity of a sloping ground, for structural design of the retrofitted or completely repaired structures should be discussed their reinforcing and updating on request of the modern city which expediency should be confirmed by feasibility study. It is obvious that the choice of the effective structural solution of the clamping retaining walls is possible only on the basis of careful calculations taking into account geotechnical conditions of a foundations and construction of such structures. Complexity of such calculations and installation is that it is necessary to consider a set of various factors: real stratification of soil and sequence of loading on the basis; complicated geometry of a construction site, already built (existing) structures and a terrain topography; nonlinear properties of soil bases (work often outside a linear stage: slipping between layers, deformations at the large pulling-out loadings, etc.) ; an assessment of the loads arising in structural design at uneven settlements. Fully the accounting of the given factors is possible only with use of numerical methods by consideration of spatial models for interaction of the clamping retaining wall and the soil bases. Scientific novelty. The clamping retaining wall has the following advantages: 1. Construction of such wall possible for any configuration and height of the terrain; 2. The material consumption for construction of such wall is more rational. 3. Construction of such wall doesn't require large space. 4. Allows to experts variety of opportunities for creating unique architectural forms along the length of work space. Practical importance. Three types of zones of a complicated terrain are allocated, where possible effective use of the clamping retaining wall: city zone, a zone with negative anthropogenic impact and industrial zone.
