On Noise Control of the Environment in Advanced Living District

The living environment is becoming more and more important,one of the main elements which affect it is noises.This paper takes the Zhonghuafang for example,to research how the whole planning and the designing for the living district affect the control of noises.Applying architectural technology,in order to cut down noises,a sound screen around the site is made and the distinctive constitution for the buildings is designed.The methods of disposing noises are proposed to make sure that the residents of the advanced living district are content with the living environment.     

Control and Analysis on Environmental Object of Construction Project

With social development, the environment has become one of the major topics in human life. Although the construction project may improve economy and environment, it also may exert negative impact on environment. Cost, schedule and quality are three important objectives of construction project and on the objective of environment have not been focused. The author of this paper reiterated the importance of environmental control for the construction project and key areas to be focused on during the whole process of construction project.     

Construction of Urban Barrier Free Environment Based on Dual-core Model

According to the investigations of urban barrier free facilities, there have been lots of progresses in constructions of barrier free in cities recently. But there are no systematic barrier free facilities in these cities, which would restrict the function and effect of urban barrier free facilities for the handicapped and the elder. This paper puts forward that there should be a development from the urban barrier free facilities to the urban barrier free environment. There are two parts in the barrier free environment,that is the hardy environment and soft environment. Finally,an in-series connection two-core model of barrier free environment has been designed and discussed.
