Study of the Effects of Rainfall Infiltration on Stability of Geocell Protection of Slope Guangyue Wang 1, a, Yan Han 1,b 1School of Civil Engineering, Shandong University, NO 17923 Jingshi Road, Jinan, China P R awgyue@sdu.edu.cn, b hanyansdu@sina.com Keywords: geocell; rainfall infiltration; stability; moisture content; slope angle Abstract.
Therefore, stability research on geocell protection of slope during rainfall has very important engineering significance, and it provides theoretical basis for geocell construction.
Engineering practice shows that the slope runoff is always shallow flow and the depth can reach about 20mm under a rainstorm.

Pavement Performance Study of Construction Waste and River Sludge Used as Subgrade Filling Chen Zhaoxia1,a , Wang ling 2,b and Wei Lianyu 3,c 1,2,3School of Civil Engineering, Hebei University of Technology, Tianjin 300132, China alllczx@126.com , bwlark@sina.com , cwly57@126.com Key words: River silt, Construction waste, Sub grade, Pavement performance Abstract: In this paper, the feasibility of river sludge subgrade with construction waste is studied through CBR test and limit moisture content test.
And the blending ratio which is appropriate to this process is obtained for engineering applications.
When adding 35% in construction waste, the bearing capacity of mixture has a peak, therefore, mixing ratio of construction waste should be properly selected in practical engineering applications.

Design Method of the Temporary Support Structure in Building Construction Fankui Zeng1, a, Changming Hu2,b and Xingcai Liu2,c 1College of Architectural engineering, Qingdao Agriculture University, Qingdao, China 2 School of Civil engineering, Xi’an University of Architecture and Technology, Xi’an, China afankuizeng@126.com, bhu.tm@163.com, clxc16050220@163.com Key words: Temporary Support Structure; Standard Structure; Equivalent Notional Lateral Loads Abstract.
However, it ought to be clear that the calculation model of temporary support should be combined and coordinated with the present structural engineering theory and standard.
As there are many different types of initial imperfection of frame, which are difficult to identify, equivalent notional lateral loads are substituted for the effect of the generalized initial imperfection in order to facilitate engineering design and construction.
