In order to make it simple in practical engineering applications and can provide reference value for practical engineering, from the viewpoint of engineering application, this paper tries to find out a LFG model which is simple, contain fewer parameters, can accurately simulate the gas production situation of actual landfill site, and suitable for the characters of Chinese MSW component.

Steady State Response of Compressible Fractional Derivative Viscoelastic Thick-walled Cylinder Linchao Liu1, a, Lie Yu2,b ,Huanxin Yu3,c 1Schoolof Civil Engineering, Xinyang Normal University, Xinyang, Henan, 464000, China 2Zhejiang Yijian Construction Co.
Introduction Thick -walled cylinders have been widely used in practical engineering [1], such as the static deformation analysis of hydraulic elastic bulging roller and the retaining ring, the design of pressure vessel, pipeline engineering and so on.
Thick -walled cylinders by the action of internal pressure are common engineering structure, and also are the classic example of elastic and plastic mechanics [2].

Analyzing Remaining Life Non-probability Reliability and Parameter Sensitivity for Pipeline Subjected to Corrosion Xindang He1,a, Wenxuan Gou1,b, Zongzhan Gao1,c, Yao Li2,d and Fei Gao2,e 1 Institute of Aircraft Reliability Engineering, School of Mechanics, Civil Engineering and Architecture, Northwestern Polytechnical University, Xi’an, 710072, P.
Unfortunately, sufficient experimental samples are not always available or sometimes are too expensive to obtain, especially in many practical engineering problems.
Through the convex model, it is possible to conduct the uncertainty analysis and reliability design for many complex engineering problems lacking sufficient information.

The corrosion prevention research of Long-span non-uniform continuous steel bridges Zilin li1, 2,a, Hongyi Ding1,b, Yi Du2,c and Jiang Xue1,d 1Tianjin University School of Civil Engineering, Tianjin 300072, China 2Tianjin Key Laboratory of Soft Soil Characteristics and Engineering Environment, Tianjin Institute of Urban Construction, Tianjin 300384, China ahebeigaomuying@163.com, b439484315@qq.com, cdyandtq@163.com, dxuejiang04@163.com Keywords: steel bridge; corrosion; anti-corrosion; painting protection.
At this stage, many bridges have been severely corroded, improvement of the corrosion process is also drawing of more and more attention in the design of bridge engineering.
However, due to the backwardness of the anti-corrosion technology and not enough emphasis, some steel bridges rust, caused serious engineering accidents, such as the lasso rust off accident of Haiyin Bridge in Guangdong and suspender corrosion caused by falling deck accident of Yibin arch bridge in Sichuan, these two bridges, from being completed to occurred the accident, were just used less than 10 years.
The construction technology of Coating plays a very important role in the anti-corrosion engineering, to strengthen the construction supervision and reform construction techniques can effectively improve the corrosion protection effect.

Optimal placement of triaxial accelerometers using modal kinetic energy method Tinghua Yi1,a, Xiang Wang1,b and Hongnan Li1,c 1 School of Civil Engineering, Faculty of Infrastructure Engineering, Dalian University of Technology, Dalian, 116023, China a yth@dlut.edu.cn, bsduangel2008@126.com, c hnli@dlut.edu.cn Keywords: Optimal sensor placement, Effective independence algorithm, Modal kinetic energy, Triaxial accelerometer.
Obviously, the actual target modes are not available to aid the test engineer in placement of the sensors prior to the test.
It has developed the traditional experience technology that needs engineers to select the structure position with larger amplitude to place sensors by comparing the measuring point modal kinetic energy.
