China's economy is continuously developing towards modernization, and the construction industry should also follow the road of modernization. Economic construction cost is an important part of the construction industry, so we should pay more attention to economic construction cost management. Proper management of the economic cost of construction can make it more competitive and further expand the scale of construction enterprises, thus promoting the development of construction industry. This paper mainly analyzes and explores how to optimize the cost management in the construction economic management, and puts forward the corresponding optimization measures.展开更多

At present economic benefit evaluation system of the UHV power grid is driving to maturity stage on the whole at home and abroad, but it invariably tends to regard social benefits as part of economic benefits, without evaluating social benefit separately. The social benefit evaluation model of UHV power grid is built in case of sufficient investigation. The differentials between social benefit and social cost are calculated respectively by three kinds of solutions according to the constructed social cost evaluation index system and social benefits evaluation index system, conclusion that UHV power grid transmission has better social benefits can be reached by contrastively analyzing the social three kinds of solutions corresponding to benefits. At last, the evaluation model and method are verified and analyzed through the analysis of engineering projects.展开更多

At present, China can independently produce 7-core, 19-core, 37-core and 61-core stranded carbon fiber core, and can cooperate with aluminum wires to form stranded carbon fiber overhead conductors of 95/20-2000/400 mm in various specifications. It can be used for new construction, capacity expansion and reconstruction, extra-large span, extra-high voltage, extra-large cross-section and other lines. Stranded carbon fiber conductor (ACMCC) is composed of stranded carbon fiber core and aluminum/aluminum alloy conductor. The core of carbon fiber is composed of a plurality of T700 and T800 carbon fiber tows, which are impregnated with high-temperature resistant epoxy resin and wrapped with high-temperature resistant fibers to form strands;then several strands are twisted into 7-core, 19-core, 37-core and 61-core carbon fiber cores, which are cured at high temperature. Stranded carbon fiber wire has the advantages of light weight, high breaking force, high temperature resistance, high elastic modulus and low linear expansion coefficient. When the conductor cross-sectional area is the same, the maximum cross-sectional flow is 2.6 times of that of ordinary steel-reinforced aluminum stranded wire. When the cross-sectional area of the conductor is the same, taking the sag at 160℃ as an example, it is 0.7 times that of the heat-resistant road alloy conductor (the smaller the sag, the better). When the cross-sectional area of the wire is the same, its weight is 0.8 times that of other wires.展开更多

In order to achieve benefit maximization, the meta-synthesis management for the government-led urban complex construction project is studied. In order to combine theory and practice, several typical government-led urban complex construction project cases, such as Guangzhou Higher Education Mega Center and Guangzhou International Financial City etc. are examined. These examples point to the feasibility of government-led meta-synthesis management and demonstrate the benefits that can be achieved through this model.展开更多
