Abstract: A long lasting project, quality is priority. The quality directly determines the success of project. The excellence of a building quality is not only the pulchritude of a countrys construction, but also the guarantee of safety of life and wealth. However, due to non-standardizing of construction market and disarray of internal management, the quality accident often occurred. This paper, based on engineering practice in projects, analyzes causes for common construction quality accident from design, materials construction supervision and some other factors, puts forward some typical engineering examples, and offers corresponding preventive measures to reduce the occurrence of construction quality accident.

Abstract: The fire in high-rise buildings is perhaps more dangerous than those occur in normal buildings because of the strong stack effect and wind effect on the fire. The wind effects on the wind flame spread across the exterior wall of the high rise building are studied in this paper by the numerical methods. The results show that high wind speed will change the wind flame spread direction and make the room inclined above the fire room more danger, especially the room at the same floor adjacent to the fire room. Special passive fire protection measures should be taken under these kinds of conditions.

Abstract: Geographical differences of traditional village exist objectively in Henan province, China. With learning geographical zoning methods, this paper is trying to zone processing through a comprehensive comparison of the formation of traditional villages area in Henan, in which the main factors such as comprehensive natural factors, economic factors, cultural factors are considered.

Abstract: A Evolution Model of the Express Freight Network is proposed based on the evolution theory of complex weighting network. The freight demands and space distance are considered into the preferential attachment scheme. Applying the model on the evolution of the express freight trains service network by China Railway Express, results show that the model is capable to embody the evolution laws with some indices slightly better than the real network.

Abstract: Through the use of investigation method of line-point, and the field investigation and study of the ancient city wall of Xunxian County historical area of traditional residential architecture, key historical relics and characteristics of the status quo, this paper summarizes the courtyard layout, material, construction technology and geographical environment of Xunxian County traditional residential area to adapt to the historical characteristics and cultural value. The ancient city wall of historical district is discussed to explore a retains for its original culture, and meet the needs of the development of city while protecting the history and the ancient city of the whole area of the long history of cultural by "Point-Line-Face" update strategy.

Abstract: This paper puts forward the index system of evaluating performance of agritainment supply chain from three attribute domains, i.e. operation domain, hierarchy domain and composition domain, uses entropy technology and analytic hierarchy process to carry on the evaluation of service performance and probes into the application of agritainment supply chain theory in practice. It is quite important on enhancing the competitive power of the whole agritainment supply chain as well as the node enterprises in the agritainment supply chain. Finally, three problems that need further study in this field are pointed out.

Abstract: According to the city development level and the regional difference, selecting 10 main cities of China and using the monthly average date of house price about three years, the effect of relationship between cities prices of different levels of development and the region in short-term was studed through the unit root test by using the method of VAR analysis model and the pulse and variance. The results show that, the rate of increase in housing prices in China between different city in short-term are clearly linked, the changes of overall level of first-tier cities affect the more rational second-tiers housing prices next period, which has a significant influence on the second-tier city to the same regions three-tier city next period. The impact of China's city structured relationship in housing prices is figured out.

Abstract: Vertical spread of opening spill plume from underground garage fire is studied by FDS. How can cornice barrier prevent the vertical spread of opening spill plume under the effect of the thermal buoyancy is analyzed. Optimal technical solutions and design parameters are proposed to improve the fire safety of underground building and adjacent buildings. This study can provide theoretical and technical reference for the underground building design.

Abstract: This paper puts forward new traffic rules and signal dispensation formula in Y-intersection under influence of pedestrian, qualitatively gives the proof of average passing through time ratio of each road in Y-intersection and provides new ideas for passing through time ratio in general intersections.

Abstract: The construction industry, as a traditional Chinese industry, its information construction level is obviously lower than other industries. In order to enhance construction productivity and reduce resource consumption, construction industry must be done for informational reform. The Building Life-cycle Management (BLM) and the Building Information Model (BIM) contain the abroad forerunners technique of establishing and managing construction information, which realize the whole process management of the construction item and whole life span of the information. This paper introduces the basic circumstance of BIM and BLM technology, analyzes the technique of BIM and BLM in the opportunity of the Chinese applied expansion, and puts forward the problem being faced and the motive to be pull.
