FIELD: construction.

SUBSTANCE: invention relates to hydrotechnical construction, namely to soil dams built in areas with high seismicity. The invention is aimed at the reduction of cost of the structure and increase of the damping ability of the seismoisolating dam layer. The aseismic soil dam built in narrow cross sections includes the main soil part of the dam body and the seismoisolating layer with dynamic characteristics significantly differing from those of the soil of the main part of the dam body. The seismoisolating layer is located along the whole contact of the dam with the base and boards of the cross section (canyon). The seismoisolating layer is formed by the installation into this layer of inclusions in the form of similar utilised metal-cord tyres from cars, which cavities are filled with gumbrine. The tyres are arranged parallel to the base and boards of the cross section (canyon) with an equal step chequerwiseboth in the same row, and between rows, the quantity of which is no less than two.

EFFECT: design features of the offered design of the seismoisolating layer allow weakening more effectively seismic waves at the expense of an increased damping and diffraction ability.

SUBSTANCE: earthquake resistant subsurface dam being constructed in broad sites, comprises the upper main part of the dam body and seismic isolation layer of the dam body located between the upper main part of the dam body and base, dynamic characteristics of which are significantly different from those of subsurface of the main part of the dam body. Seismic isolation layer is formed by installing inclusions in the form of one-type recycled metal-cord tire casings of heavy vehicles in this layer. The cavities of these tire casings are filled with gumbrine. The tire casings are arranged horizontally at regular intervals in staggered order and in the horizontal plane. In the vertical plane the tire casings also arrange at regular interval in staggered order with number of rows not less than two. Design features of the proposed structure of seismic isolation layer permits to attenuate seismic waves more effectively due to the increased damping capacity and diffraction.

SUBSTANCE: static, dynamic or vibration sensing is carried out preliminary at the selected points to the depth from 1 m with respect to the top of the earth fill. At the same time the samples of compacted soil of undisturbed structure are selected in order to determine the moisture and density of skeleton of the specified soil from several drilled wells at points at a distance of not more than 1 metre in plan from sensing points. Laboratory researches of standard compaction with definition of compacting factor depending on the density of soil skeleton, are carried out on the selected samples of soils from the body of compacted fill. Construction of correlation dependence is performed between the specified values of compaction factor and values of the resistance to penetration of standard cone into the soil during sensing, taking into account determinations previously performed in the laboratory followed by evaluation of compaction quality of the earth fill.

EFFECT: improving the accuracy of definition and identifying the areas of non-compacted soil for its subsequent local postcompaction.

SUBSTANCE: invention is designed for use in hydraulic engineering, in particular, to create dams of tailing dumps in areas with significant anthropogenic load on water facilities. The method includes preparation of the base for the dam and laying of soil material into the dam bank. Soil material is represented by anthropogenic bottom deposits of contaminated water facilities having permissible filtration capacity and sufficient strength according to hydroeconomic calculations. Anthropogenic bottom deposits are previously prepared by dehydration in containers from geotextile material to moisture of 40-50% and compaction under by gravity on a specially prepared site. Afterwards containers with dehydrated residue are delivered to the place of construction by dump trucks and are laid by mobile cranes in layers. The promising direction is usage of this device in areas of far north, since in these areas usually there are no sufficient soil materials suitable for creation of antifiltration elements. Local materials used to fill the dam bank are in permafrost condition and their usage causes significant difficulties. Utilisation of heterogeneous bottom deposits is provided, environmental compatibility and fail-safety of dam operation increase, erected structures are more stable.

EFFECT: reduced filtration losses, timing of construction, minimised complexity and labour intensiveness of works.
