Due to the particular bed composition of mountainous river, experiment was carried out combining the two dimensional mathematical model and the local physical model. Boundary conditions of the local physical model were provided by the results of mathematical mode. The river-bed scouring around and bilateral cofferdam of jiangjin-guanyinyan bridge's 10# pie were studied. Results show that the maximum scour depth gradually move upward to the current-rushing point with the increasing of the inflow. Comparing the local scour of theoretical value with the experiment result, it is feasible that the general scouring could be neglected when calculating the pier scouring of mountainous stream.

According to current quality defects of external heat insulating system, a new external wall insulation system was designed by making full use of air's heat insulation performance. This paper makes a comparative analysis of it and the other exterior wall external insulation systems recommended in the existing national standards (06J908-1), and conducts feasible studies from the evaluation parameters of energy-saving and thermal performance: heat transfer coefficient K indicators, energy consumption rates and economic indicators. It is proved that the new system's indicators are better than other similar existing energy-saving systems in the market of the building energy-saving insulation design. It can greatly improve the energy-saving insulation efficiency of external walls; reduce production cost and construction refuse as well. Furthermore, the paper provides theory basis for the promotion of it in both Henan Province and other areas with similar weather conditions.

The turbid removal experiments were conducted with hydrated manganese dioxide that produced by deoxidization of KMnO4 for simulated water and Tiansha River water. And the factors that influence the coagulation and the effects of coagulation were analyzed in this study. The results showed that hydrated manganese dioxide was one kind of effective water treatment agent which has significant removal effect of turbid in water. The turbidity in Tiansha River water can be removed more than 95% with the addition of 13 mg/l of hydrated manganese dioxide in tests.

In an effort to facilitate wider use of the large amount of data collected to support “real-time” ITS applications, many provinces and local cities have endeavored to create ITS Data Management Systems to provide the travel information services under the National ITS Architecture. Unfortunately, experience with ITS data management systems revealed that usage of the systems has been rather light,many date had been wasted, and it was clear that a ITS data management system must continue to evolve as user requirements and data availability changed. To address these needs, the research described in this paper was conducted in an effort to improve the data management system usages through closer attention to user requirements and by a focus on the development of data processing tools for users. and a framework for developing the ITS data management system to meet user requirements was presented. which can been used to guide the research and development of ITS data management system in china.

A deep treatment on purification of effluent of second treatment for rural domestic sewage in Chongming-Island by enhanced ecological floating raft was performed. Microbial biomass carbon, nitrogen and phosphorus in fiber padding of enhanced ecological floating raft was measured using the chloroform fumigation incubation method, and variation characteristic of the microbial biomass content in time and space was studied. The results showed that in the same season microbial biomass carbon and nitrogen in forepart was greater than in posterior segment and in lower layer than in upper layer, while phosphorus content has the same law with carbon and nitrogen in transverse direction and the opposite law in longitudinal direction; In different season microbial biomass carbon, nitrogen and phosphorus contents were highest in July and were similar in the other seasons. Microbial biomass carbon and nitrogen contents were respectively higher than background value by 2.21∼9.26 times and 1.93∼8.12 times.

Engineering properties of cement with coal gangue was studied to determine the compressive strength, freeze-thaw and shrinkage characteristics of the material. The composition of coal gangue was determined using the screening test; the liquid limit, plastic limit and water ratio of the cement with coal gangue were measured using the Liquid and Plastic Limit Joint Detector. The optimal water ratio of the cement with coal gangue was measured based on the water absorption rate of coal gangue and the cement water ratio. At the optimal water ratio the results indicated that the unconfined compressive strength, freeze-thaw characteristic and roadway contractibility can be improved by adding 10% cement into coal gangue.

Based on project practice of double-row piles retaining structure in Huaneng Fuzhou power plant, multi-schemes of supporting and retaining structure have been contrasted and the optimal scheme is recommended. To deal with the soil loss between piles, scheme of small interval and small diameter pipes shall be employed and jet grouting shall be used to improve the soil between piles, so that the soil shall be self-stable on the front surface. The success of the project ensures the operation of the existing power plant and construction of the building plant, which is one avail application case for reference of similar project.

This paper presents experimental research and analysis of energy efficiency for direct radiant floor heating system with ASHP (air source heat pump). An experimental platform was built, and the performance of ASHP, heating effect and energy consumption of heating system were studied. The results show that the indoor heat load can be well met when the output capacity of ASHP runs at 30%, in which the floor surface temperature and indoor air temperature were reached at 26 °C, 22 °C, respectively. Vertical temperature field can well met the requirements of indoor thermal comfort. Besides, the paper examines heating performance for different envelope, the results indicate that as the condensing coil spacing decreases, the indoor heating effect gets better, but the consumption of energy and tubes increase. Finally, testing the hourly energy efficiency ratio of heating system, and comparing energy efficiency of different technologies, the results point out that radiant floor heating system with ASHP has the best energy efficiency and the obvious advantage of energy saving compared with other heating technologies.
