- Authors:
- V. A. Kougiya
- O. P. Sergeev
Arched bridges with suspension brackets of cables are built over the river Ohta in Saint Petersburg and the river Ishim in Astana (Kazakhstan). Each semi-arch was carried out of separate units from supporting block of the arch tightening. There are given the formulas for calculating the precision of semi-arch jointing depending on the fabrication accuracy and dimensions of its elements, on the shape and size of the arch span. Calculation examples are given for the arch bridge construction over the river Ishim in Astana.

Rationale for the accuracy and parameters of cadastral surveying of land urbanized territories
It is shown that the position of landmarks urban land area up to 2 hectares should be determined with errors in relation to the items city geodetic network mt = 0,05 m, for sites larger area – mt = 0,10 m. Formulas calculate the parameters theodolite moves (angular and linear residuals, stroke lengths and the number of sides) and the parameters of the cadastral survey (distances to landmarks).

Development of geomechanical provision room-and-pillar system of rock burst ore deposits at great depths
- Authors:
- D. V. Sidorov
Considered directions of geomechanical provide room-and-pillar system rock burst ore deposits at great depths, consisting in the modernization and development of the scientific basis of the complex methods for determining the allowable size of worked-out areas, the size of the roof chamber, the size a protective of the pillars, the size of the chamber – pillars, including with regard to their dynamic burst, and creating automated software system for long-term forecasting of the geodynamic state of the ore deposit and shockproof advance planning of activities to improve the safety of mining operations.
