| 1. | Despite the decisions made repeatedly at various conferences and seminars, there are still no scientific design guidelines. As a consequence of this, crucial decisions are made without sufficient substantiation and thorough evaluation of the decisions made. |
| 2. | Research institutes should not be limited to collecting data on settlements and temperature and seepage regimes of dams, but on the basis of data already available should give clear-cut standards and regulations for the design of earth structures in the northern construction-climatic zone. |
| 3. | The construction of transition zones between the rock fill of the downstream shoulder and foundation, drainage blanket, and relief drainage is mandatory in all cases when the foundation is composed of fractured rocks covered by a diverse stratum of loose soils of various origin. |

The core-filters-drainage system should be a zone of increased attention when performing works and assigning the characteristics of the soils being placed.
As far as possible, it is necessary to change to dam designs with narrow cores protected by transition zones and developed drainage. When constructing such dams in the winter, especially in the case of heavy snow falls, it is easier to check the quality of placing the material in the zone of increased attention — core-filter. 相似文献

The main legislative documents in the field of environmental protection and ecological standards for newly developed equipment of thermal power plants (TTP) of Russia are presented. Problems of raising the efficiency TTP and reducing harmful emissions are considered. Modern methods and process for lowering nitrogen oxide emissions for different kinds of fuel, fields of application of sulfur-removing technologies, and ways for updating fly-ash collectors are discussed. The tendency to tightening of standards regulating the volume of contaminating substances is shown. Data on TTP wastewaters and maximum permissible concentrations (MPC) of primary contaminants are presented. Reduction of atmospheric emissions and of contaminating due TTP wastewaters is estimated until 2010.__________Translated from Elektricheskie Stantsii, No. 1, January 2005, pp. 17–27 相似文献
