Study Of College-student Entrepreneurial Opportunity Recognition Influential Factors Based On Multiple Cases

In recent years, China’s bridge construction works are powerful development phase tobuild a country from the stage. At the same time the negative impact due to the extensiveconstruction of bridge engineering for the environment is also very serious. Construction ofbridge engineering for sustainable development has been widely recognized as aninternational field of structural engineering, bridge engineering in order to achievesustainable development, the center is working to adapt to the environment so that the levelof economic development, the focus of bridge engineering research in addition toenvironmental issues, as well as for the cost of their life cycle environmental impact. Eventhe study of the life cycle cost of the environmental impact in terms of material alreadyembarked on industrial and ecological products, but research is still in its initial phase. Thus,it is necessary to approach the cost analysis of the life cycle environmental impacts of bridgeengineering research and demonstration system.This article will Hunan Provincial Natural Science Foundation project " Evaluation ofbridge engineering research lifecycle environmental impact " as a basis for the wording ofthis article, in order to reduce the environmental impact of bridge engineering life cyclecosts, protect the environment as a starting point, the life cycle cost evaluation theory andlife cycle analysis theory as the basic theory of this article rely on the life-cycleenvironmental impacts of bridge engineering costs discussed the bridge project life-cyclecost analysis of environmental impact models built out, followed by a brief introduction tothe major research findings:1.Evaluation theory and life-cycle cost analysis theory through the life cycle, life cycleanalysis of the environmental impacts of bridge engineering complexity and diversity offactors, in line with the basic principles of integrity, scientific, professional, etc., the costof the bridge project environmental impact the types are divided into five categories: waterpollution costs, the cost of air pollution, noise pollution costs, resource consumption andcosts of solid waste pollution costs, environmental impacts of bridge engineering life cyclecost analysis indicator system created.2.through the bridge engineering, respectively, from the design, production and processing of raw materials, the construction phase, operation and maintenance as well asbridges abandoned five stages of the life cycle are discussed, based on the various stages ofthe environmental impact of its cost type and characteristics of the various stages of theapplicable choice the calculation method of calculating the cost of environmental impactindicators, and the environmental load and corresponding economic value linked to themulti-phase bridge project life cycle environmental impact of the cost to undertake acomprehensive multi-factor analysis, the final completion of the bridge project life-cyclecost analysis environment Construction of the model.3.Use the bridge project life cycle environmental cost analysis model of the bridgelifecycle environmental impact costs for simple analysis. The results showed that during thelife cycle of the bridge, resulting in the most significant impact on the environment and theimpact on the costs of raw materials and processing stages of production, cost andenvironmental impact of all, the environmental impact of resource consumption costs wouldhave the most significant effect. This method can be used as the basic bridge engineeringlife cycle environmental impact of the cost of quantitative methods for comprehensiveevaluation of bridge engineering environment.
