But such kind of evaluation system has not been proposed in China. In this study, an evaluation index system is specifically developed to evaluate deep groundwater management efficiency. It is composed of three first-level indicators(law enforcement capability, management ability, and management effectiveness) and eleven second-level indicators. The second-level indicators include seven mandatory indicators and four optional indicators. Piecewise linear function is used to normalize the quantitative indicators, and expert scoring method and questionnaire survey method are used to normalize the qualitative indicators. Then a comprehensive indicator weighting evaluation method is used to evaluate the first-level indicators and the target topic. A case study is carried out to evaluate deep groundwater management efficiency in Tianjin City. According to the evaluation score in each period, the management efficiency of every district in Tianjin City gradually improved. The overall evaluation score in the early deep groundwater extraction period is 0.12. After a series of deep groundwater protection efforts, this score reached to 0.61 in 2007, and met the regulation criteria. The evaluation results also showed that the further groundwater management efforts in Tianjin City should be focused on building a dynamic database to collect comprehensive deep well-log data; and on a reasonable design and distribution of the groundwater monitoring network. It demonstrated that the index system is suitable to locate the deficiencies of current groundwater management systems and to guide further improvements. It can then be used to protect deep groundwater. 展开更多

There are more than eight different design standards in use for the existing railway bridges in China, which have different applicabilities for bridges built in different periods. In this paper, the design load standards in different periods are introduced and compared; The working status of the railway is investigated. According to the developing trend of separating passenger and freight transports, by comparing the computed results of the bridge effect and the fatigue cumulative damage, the applicabilities of bearing capacity and fatigue are analyzed for existing bridges. The results indicate that the bearing capacities of 99% existing bridges are suitable for the demand of 26.5 t (axle-weight) freight trains. However, for culverts, bridges with spans less than 20 m, longitudinal and transverse beams of through bridges, suspenders of truss bridges and other locally-stressed members should be evaluated and reinforced due to the increasing axle-weight. 展开更多

The basic element in any sustainable dam project is safety, which includes the following safety elements: O structural safety, dam safety monitoring, operational safety and maintenance, and emergency planning. Long-term safety primarily includes the analysis of all hazards affecting the project; that is, hazards from the natural environment, hazards from the man-made environment, and project-specific and site-specific hazards. The special features of the seismic safety of dams are discussed. Large dams were the first structures to be systematically designed against earthquakes, starting in the 1930s. How- ever, the seismic safety of older dams is unknown, as most were designed using seismic design criteria and methods of dynamic analysis that are considered obsolete today. Therefore, we need to reevaluate the seismic safety of existing dams based on current state-of-the-art practices and rehabilitate deficient dams. For large dams, a site-specific seismic hazard analysis is usually recommended. Today, large dams and the safety-relevant elements used for controlling the reservoir after a strong earthquake must be able to withstand the ground motions of a safety evaluation earthquake. The ground motion parameters can be determined either by a probabilistic or a deterministic seismic hazard analysis. During strong earthquakes, inelastic deformations may occur in a dam; therefore, the seismic analysis has to be car- ried out in the time domain. Furthermore, earthquakes create multiple seismic hazards for dams such as ground shaking, fault movements, mass movements, and others. The ground motions needed by the dam engineer are not real earthquake ground motions but models of the ground motion, which allow the safe design of dams. It must also be kept in mind that darn safety evaluations must be carried out several times during the long life of large storage dams. These features are discussed in this paper. 展开更多

Considering that buildings represent 40% of greenhouse gases and approximately 10% of global gross domestic product, the target the building industry has to accomplish is to get to a high quality and low carbon living, by reducing carbon emission by 2050, as said by Energy Performance of Buildings Directive. Considering these needs, designers, manufacturers and construction companies should be able to make use of web and design tools for collecting and inventorying a large variety of environmentally friendly materials, through a specific database that encloses low carbon certified products and eco-labeled ones. The eco-labels are internationally identified as the best tools to encourage the spread of green products and low carbon notions, even if in Europe, there is no specific tool to be used. The project called LoCaMat (Low Carbon Material Database) will act as the first Italian and European database that encompasses multiple data on certified green materials to be used for the construction sector, making buildings climate change resilient, ensuring an efficient use of energy and resources, getting to a complete life cycle assessment for buildings materials and components, encompassing, for the first time, green data and every kind of environmental specs for sustainable design and green practice. 展开更多

Design-manufacturing chain (D-MC) is the most important link of the supply chain with the greatest possibility in cost reduction. How to strengthen the effective management of interracial relationship between designer and manufacturer and increase the efficency of interface management concerns the efficiency of the whole supply chain. In order to evaluate and improve the impacts of D-MC interfacial relationship, first we should construct the evaluation index system and then we should analyze the total cost and benefit of the interfacial relationship betterment, including the cost of member units in D-MC, the opportunity cost of cooperation partners, and the market returns resulted from the interfacial relationship improvement, which will advance the whole supply chain efficiency as well as enhance the management performance of D-MC. 展开更多
