A New Formula for Critical Depth of the U-shaped channels Fengling Lia, Hui Wenb, Xuguan Linc Department of architecture and civil engineering , Huizhou University , Huizhou, Guangdong, 516007, China ammlflmm@163.com, bwenhui-hzu@163.com, czhxuguan@163.com Key words: U-shaped channel; approximate solution; critical depth Abstract: U-shaped section channel is widely used in water conservancy projects.
The engineering case shows that the proposed formulae are simple and accurate.
What’s more, it’s very convenient for the engineering designers to work directly in the design of the U-shaped section channel.

Study on Fire Design in Xuefengshan Highway Tunnel Yonglin An 1, a 1School of Civil Engineering, Hunan University of Science and Technology, Xiangtan 411201, China aaylcsu@163.com Keywords: tunnel engineering, evacuation, fire safety Abstract.
It is a new concept of fire design by means of engineering method to predict and evaluate fire risk in quantity so as to optimize fire prevention design of buildings[1,2].

In addition, in order to implement the agreements smoothly, some subsidy policies, a special advisory committee and advanced technology in environment engineering are also necessary. 3.2 The Deficiencies of LTA1 It should be noted that some participating sector did not achieve their established targets successfully.
Under this situation, Chinese government should learn from LTA1, and make following improvements: Firstly, should formulate and perfect relevant policies, establish supervision and services system according to emission reduction status quo of China [11]; Secondly, should guide the industry to draw emission reduction plans according to general framework; Thirdly, should pay attention to the role of the third-party organization and the recommendations proposed by them, in order to avoid "capturing" the relevant provisions and sacrificing the public’s interest; Fourthly, should sign agreements with energy-intensive industries ,and set pilot projects for SMEs; Lastly, should devote more resource to develop advanced technology in environment engineering.

Network Security Management for Railway Out-of-gauge and Enhanced-load Goods Dispatching System Yinggui Zhang1,2, a, Dingyou Lei2,b , Qiongfang Zeng2,c 1School of Civil Engineering, Central South University, Changsha, Hunan, 410004, China 2 School of Traffic and Transportation Engineering, Central South University, Changsha, Hunan, 410004, China aygzhang@csu.edu.cn, bding@csu.edu.cn, czqf1990@gmail.com Keywords: railway out-of-gauge and enhanced-load goods (ROEG), ROEG dispatching system, network framework and architecture, security technology, security management Abstract.
Railway out-of-gauge and enhanced-load goods (ROEG) transport organization with risky, costly and difficult characteristics is the system engineering.
ROEG transport refers to nearly all railway transport departments, such as dispatching, train operations, locomotive operations, track maintenance and power supply sections, and thus its organization is a rather complex engineering system [1].
