Abstract: This paper outlines the research status of solar radiation at home and abroad, it discusses the weather cloud, greenhouse covering materials and other factors on the effect of light greenhouse environment, at the same time it summarizes the initial results of light greenhouse environment model simulation research, it also points out the research direction of unsolved problems and future on the light greenhouse environment, we consider the sunlight greenhouse with guidance and reference from the angle of light environmental.

Abstract: In order to better play an important role in the subway transit system to achieve its dominant position, it is necessary to establish a good feeding system and interface transfer system. On the basis of the current study urban passenger transfer characteristics, the study of urban rail transport passenger transfer is essential. Shenyang Subway Line 1 eased the pressure on the ground transportation of city to a large extent from the completion of construction to be put into use. In this paper, inquirer survey method, induction contrast method and comparative analysis method are selected to investigate the traffic of the each site in Shenyang subway lines, and analyze the characteristics of the passenger transfer, so that the subway planning operator can be gradually improved and the operational organization can be better guided.

Abstract: In the earthwork allocation, the deployment of Turkish solving method commonly used in the current Planning Act the "tabular method" to improve a "folder on both sides of the table to force the working method." This method can improve efficiency, reduce testing and other steps, and can be more accurate and efficient optimal solution.

Abstract: In the foundry industry, the main solid waste is the foundry waste sand, casting cupola dust and slag, which causes environmental pollution and becomes a bottleneck restricting the development of the foundry industry. The main components of the foundry waste sand and slag generated by casting are siliceous and calcareous granular materials, which meet the needs of engineering construction materials, they have a broad application prospect. In this paper, the investigation and analysis of the foundry waste sand and slag have been carried on about the research and application in the engineering construction, which provide reference and basis for the application of foundry waste sand and slag in the engineering.

Abstract: Environment problems have attracted common concern and have great impact on the construction industry, so we must emphasize the use of green building materials. The paper discusses the meaning, the necessity and the development strategy of green building materials.

Abstract: This paper adopts finite element method to carry out three-dimensional finite element simulation analysis for Baochuan reinforced concrete rectangular section beam-supported aqueduct. Researching variation law of the aqueduct’s stress and displacement in construction process and operating process. Analysis results show that, structure of Baochuan reinforced concrete rectangular section beam-supported aqueduct is reasonable, it meets the requirements for engineering.

Abstract: This paper made an empirical analysis on the board of supervisors system implementation effect of building materials in SMEs . The author discovered that there was no obvious linear relation between board of supervisors characteristic and the connected sale;The board of supervisors scale and the stock supervisor proportion had no remarkable influence to the connected scales; But the board of supervisors conference number every year had remarkable positive correlation with the connected procurement. The real diagnosis results had reflected that our board of supervisors was invalid to some extent in China.

Abstract: This paper uses total radiation instrument and scattered radiation instruments to test illumination irradiance in the center point of sunshine greenhouse, and compares the test data with the software model predicted data, the results show that: the radiation of fine day indoor sunshine greenhouse is generally larger than that in cloudy. The average values in fine day of outdoor observation value, outdoor simulation value, indoor observation value, indoor simulation value are 347.6, 292.3, 153.8 and 151.7, while that in cloudy day are 261.1, 262.7, 110.2and 123.9. The trend of total indoor radiation simulation value is consistent with the observation value.

Abstract: Based on LS-DYNA 3D finite element program and Holmquist Johnson Cook (HJC) model, a numerical simulation research on a new type of fiber concrete reinforced by UHMWPE fiber against 12.7 mm Armor Piercing ammunition was conducted. The results show that the simulated results to penetration depth have a good agreement with experiment data. An ACE modified formula both considering promoted tensile strength and toughness reinforced by UHMWPE fiber is proposed, whose theoretical results are very close to that of experiment and numerical simulation and can predict the penetration depth of UHMWPE fiber concrete (UFRC) well.

Abstract: To advocate and promote environmental protection building decoration materials is the inevitable trend of the development of the times is the requirement of sustainable development, also is the construction of environmental protection, healthy living security. We introduced the environmental protection building decoration material advantages, classification and the current flow of Ding green building and decoration materials, and the environmental protection building material prospects into Ding exploratory prospects.
