Remodeling of Rural Public Service Supply Mechanism under the Background of New Village Construction

Under the background of new village construction, the necessity of remodeling the supply mechanism of rural public service is expounded. It is conducive to improving the capability of public service to satisfy farmers' demand; to constructing a rural diversified public service system and improving the supply efficiency of rural public goods; to realizing the equalization of urban-rural public services to coordinate urban-rural development. Problems in the supply of Chinese rural public services are analyzed:the demand of rural public goods is enormous, governmental fiscal expenditure is insufficient; social organization is imperfect and public service capability is weak; urban-rural gap is large and the supply of pubic service is unequal; the system of rural public service is single and the functions are imperfect; the market degree of rural public service is low and the efficiency needs improving. In view of these problems, the strategies for remodeling the supply mechanism of rural public service are put forward, covering intensifying the input intensity of the government, expanding the coverage of public services; vigorously supporting the development of social organization and improving its capability of public goods; breaking through dual system and realizing the equalization of urban-rural public service; perfecting rural diversified public services and perfecting its public service functions; promoting the market progress of rural public services and improving the efficiency of public service.

Real-time and dynamic schedule optimization of construction projects on the basis of lean construction

Lean construction has been newly applied to construction industry. The best performance of a project can be achieved through the precise definition of construction product, rational work break structure, lean supply chain, decrease of resources waste, objective control and so forth. Referring to the characteristics of schedule planning of construction projects and lean construction philosophy, we proposed optimizing methodology of real-time and dynamic schedule of construction projects based on lean construction. The basis of the methodology is process reorganization and lean supply in construction enterprises. The traditional estimating method of the activity duration is fuzzy and random;however, a newly proposed lean forecasting method employs multi-components linear-regression, back-propagation artificial neural networks and learning curve. Taking account of the limited resources and the fixed duration of a project, the optimizing method of the real-time and dynamic schedule adopts the concept of resource driving. To optimize the schedule of a construction project timely and effectively, an intellectualized schedule management system was developed. It can work out the initial schedule, optimize the real-time and dynamic schedule, and display the schedule with the Gant Chart, the net-work graph and the space-time line chart. A case study was also presented to explain the proposed method.

Special Marking of 3D Networks＇ Points for the Monitoring of Modern Constructions

In order to monitor the deformations of modern constructions a local 3D network was usually being established at the surrounding area. The centering error, of both the instrument and targets, causes significant uncertainties in the determination of the x, y, z coordinates of the network＇s points. In order to assure precise centering for both the instrument and targets, not only for the accessible but also for the inaccessible network＇s points, a prototype way of marking is being implied. A special semi-permanent portable metallic stand （Photo 1） was manufactured for marking the accessible points. The stand provides forced instrument centering of the order of_＋0, lmm. It is light enough to carry, it accelerates and facilitates the centering and leveling of the instrument as well as it eliminates the time needed for the measurements. The applied laboratory checks in order to certify the suitability of its use and the provided accuracy are being described. For the inaccessible points special targets were used. The targets were put in permanent attachments （Photos 7-8）, which were also manufactured. Useful conclusions were drawn when these special accessories were used in to a 3D network, which was established for the monitoring of a new football stadium. Two measurement phases were carried out. The first one is with the stadium empty and the second one is when it was crowded （about 32000 people） during a significant football match.

Numerical Analysis of Influencing Factors on Temperature Field and Airflow Distribution of the Displacement Ventilation System

Indoor air quality and thermal comfort are important features of indoor environment. In this paper, a numerical simulation based on the k-ε model of CFD is used to analyze factors such as loading, exterior-protected construction, blowing-in rate that play an important role in the temperature field and airflow field of the displacement ventilation system. Exterior-protected construction has little influence on indoor temperature distribution of displacement ventilation systems and the influence is limited only in a small area near the external wall when the indoor heat source is the main cooling load.The height of a room has little influence on indoor temperature field, and the temperature gradient of active region is basically unchanged. In the system combined with a displacement ventilation system and a cooling system, the height also has little influence. When the cooling load is high,the indoor heat source creates a strong convective plume, which will make the average indoor air age lower, the ventilation efficiency higher and the elimination of pollutant easier. Air supply rate plays an important role in displacement ventilation systems. The increase of air supply rate that can be realized by increasing the air supply velocity and enlarging the area of air inlet will increase the mass capability of the system and diminish the vertical temperature gradient. From the comparison between simulations and experiments, it is concluded that this simulation are creditable.

Research on vertical deformation during construction of Shanghai World Financial Center

Shanghai World Financial Center is one of the highest buildings in the world, of which cumulation of vertical deformation during construction is significant and worth investigating. A refined finite element model was developed to conduct full-process analysis of construction of super-high rise buildings like Shanghai World Financial Center, in which the discrete analysis method of time-varying structures and age-adjusted effective modulus method were both used. In the finite element analysis, the whole construction process was divided into a series of stages, each with a structural system that is a part of the whole structure and with different material parameters, geometrical parameters, loading and boundary conditions. The whole construction process of Shanghai World Financial Center in consideration of creep of concrete was simulated successfully by using the finite element model and the analytical method developed. With respect to different construction stage, the total vertical deformation, inter-floor compression deformation and the relative deformation between the outer frame and the core-wall were obtained through the analysis. The comparison between the results from the stage-wise full-process analysis of construction with and without considering the creep and the results from the conventional analysis of the whole building under the total load from all self-weight and construction applied to the structure "in one go" shows that the cumulative effect on the deformation from the construction process and the creep effect need to be considered in analyzing the deformation of Shanghai World Financial Center, and the super-high rise buildings suchlike. Finally, the simulation results correlate well with the monitoring results-a proof of the feasibility and the validity of this paper.
