The Indoor Radon Concentration Measurement and Analysis in a University and its Adjacent Areas Fuliang Jiang1, a, Zengguang Yang1, b, Xiangwu Qi1, c, Xiangyang Li1 1School of Environment Protection and Safety Engineering, University of South China, Hengyang, China ajfljfd@163.com, byangzg1991@sina.com, c614509261@qq.com Key words: radon; hazards; indoor detection; dose estimation; measures and suggestions Abstract.
China proceed from the actual situation, has formulated a series of control standard of limit value of indoor radon concentration, such as Code for Indoor Environmental Pollution Control of Civil Building Engineering (GB50325-2010).
Standard provisions state that indoor radon concentration of civil building engineering (housing, hospital, kindergarten, classrooms and so on) of ClassⅠ ≤200 Bq/m3 , civil building engineering (office building, store, hotel, library and so on) of ClassⅡ ≤400 Bq/m3 [6].
From Figure 1 and Figure 2 we can see: the indoor radon concentration is higher from the wee hours to the morning and it is low at nightfall, all of which have not exceeded the limit of civil building engineering of Class II in GB50325-2010.

Route Selection of Expressway Based on VE and AHP Hongzhang Zhu 1, a, Yaoqiang Chen 2,b 1 Department of Civil Engineering,Wuhan University,China 2 Department of Civil Engineering,Wuhan University,China azhz16881688@126.com, byaoqiangchen@126.com Key words: Expressway route; Value Engineering; Analytic hierarchy process; Route selection Abstract The route selection is a very important job in the planning and construction of the expressway.
In the optimization of various route plans, value engineering (VE) was applied to make scientific decisions on the plans so that the ultimate value of the plan is reflected in economic benefit and social benefit.
Basic principle of VE and AHP 2.1 Value engineering (VE) Value engineering (VE) originates from the United States in the 1940s, and it strives to realize the necessary functions of the object at the cost of the lowest service life and is committed to the organized creative activities of functional analysis.
AHP is a typical system engineering method from qualitative analysis to quantitative analysis metasynthesis.
