21st Century General Plan and Transportation Design

Cross-body programs; third non-production use to compress 5 1998 13 to power construction, in particular, before the plant is to greatly reduce the area. 2.2.3 Optimization of coal transportation programs to reduce costs of special railway line construction in areas where conditions permit to actively promote road transport program. Special railway line to transport coal power plant scheme is currently being widely used program, but in recent years, investment in high railway line, up the momentum difficult to suppress, the power to bear. With the development of reform and opening up, constantly improve the market economy, the coal supply market has also changed. Local coal burning power plants increasing proportion of its economy is good, plus the road network continues to strengthen and improve, making the car coal has a certain competitive edge. We should take advantage of this favorable situation, in the new power plant project,[link widoczny dla zalogowanych], the pair is to transport coal by rail or road transport coal, should be determined after a comprehensive technical and economic comparison. Of all coal power plants by road vehicles should be the maximum volume limit for the analysis, for all the use of motor transport. This + one can get rid of or alleviate the long-term subject to a single power plant coal rail transport situation; the other hand, the introduction of competition mechanism can reduce the special railway line construction and rail transportation costs. 2.2.4 reasonably determine the site elevation. First, determine the elevation of the site should meet the requirements of a frequency flood level, to ensure plant safety; earth should also attach importance to balance the plant to minimize the amount of earth to open up. 1 million kw-class power plant site to raise or lower elevation 1m,[link widoczny dla zalogowanych], will affect about 100 million m. Earthwork to 3o per / m. Dollars, tens of millions of investment. Cycle power plant on a DC, because of its large circulation of water, each step 1to. Head, increasing its annual operation cost several million dollars. Also for large filling plant, filling excessive, costly not only earth, and to increase the basis of processing costs. So to change the earth in the design concept of low cost, fully aware of the elevation of the site selection is reasonable tremendous impact on investment is limited design should be an important factor in the control of foundation treatment program is 2.2.5 and the general layout of the site selection to determine the location of the main plant in one of the factors. General layout design professional to provide the geological bedrock contour line and base soil physical and mechanical properties, the main production areas of major construction load (structure) arranged in the foundation of better-I, Ⅱ class venue, in particular, should be arranged in the main plant early to deal with natural and artificial ground least-cost location, which can significantly reduce the cost of building the initial foundation treatment. 2.2.6 Design of the total figure to continue to improve the level of computer application. Although in the Electric Power Design Institute, the computer-aided design has been widely used, and the total coverage of the largest computer software chart, the highest figure, but still need to improve the application level, focusing on development and application of three-dimensional design software and roaming, which good site selection, general layout scheme comparison, pipeline collision checking, and the plant site to determine the elevation of the earth are fast and accurate means of balance. Depth of 2.3 to continue and improve the power plant site and the general layout of the site is a resource evaluation methods, but also commodities. In the reform and opening up the market economy conditions, the site as a paid transfer of goods,[link widoczny dla zalogowanych], the quantitative analysis and evaluation is essential. The power plant site and the general layout of the traditional evaluation methods are qualitative evaluation,[link widoczny dla zalogowanych], still does not have a complete, more accurate, simple method for the quantitative i Xi. Only the quantitative evaluation of the project's appraised to provide convincing quantitative data. In the future to increase the strength of the quantitative evaluation method of the existing power system based on the quantitative study focused on improving its maneuverability to further reduce the influence of human factors, appropriate evaluation methods simplified to make it easier to apply to engineering to go. 3 Conclusion In China, the seventies and eighties was a major power during the design development, publishing a large number of general layout and transportation design reference books and materials, at the time played a summary of the role of raising and training. From 9o years after the development of unit capacity from 300MW to 600MW, 900Mwi from the thermal power plant design to the design of nuclear power plant design means i have entered the computer age. At the threshold of the 21st century, need to organize experts and experienced insight, constantly sum up experience, the preparation of the new general plan transportation design books and reference materials to continuously improve the level of general layout and transportation design Newsletter 3 6 Xinhua General Hospital issued regulations Hebi Power Plant Sino-foreign cooperative feasibility study report (modified) review comments. The Sino-US joint venture project for the engineering, construction scale for the installation of 2 sets of 300Mw domestic coal-fired units,[link widoczny dla zalogowanych], and leave room for expansion. Construction model to be adopted Construction of EPC contracting approach.
