Analysis of Nonlinear Dynamic for Piles under Earthquake Loading JianGen Lv 1, a ,JianHui Qiu 1, b 1 School of Urban construction, Zhongkai University of Agriculture and Engineering, Guangzhou, China alvjiangen77@163.com(corresponding author),b153164258@qq.com Keywords: Pile foundation; nonlinear dynamic; earthquake loading Abstract.
Introduction Piles are applied widely on civil engineering extensively, because of its high bearing capacity, good stability and good adaptability to complex geological environments.
Therefore, it has been one of the research focuses in the fields of geotechnical engineering and earthquake engineering [1].

The Study on Thermal Interaction of the Underground Water Source Heat Pump’s Different Pumping/Injecting well Groups’ Arranged Modes Shumi Zhang 1,2,a , Qing Gao 1,b 1Department of Thermal Engineering, Jilin University, Jilin, Changchun 130025, China 2Changchun Architecture and Civil Engineering College, Changchun 130607, China azhangshumi2006@sina.com, bgaoqing@jlu.edu.com Keywords: Coupled model; Arranged pattern of wells; Thermal interaction Abstract.
However, different patterns on the pumping/injecting wells water temperature effect is not the same, this paper simulated and predicted the trend of the groundwater temperature in the different wells mode, analyses of simulation results and putted forward reasonable furnished well program, provided theoretical basis for the engineering practice, compensated for shortcoming of pumping/injecting well arrangement with experience, from two aspects of pumping irrigation wells spacing and number, through the coupling model establishment of groundwater flow and temperature.
distance between wells 75*20 distance between wells 112.5*30 distance between wells 150*40 Fig.5 The pumping wells surrounding temperature field under changing the spacing of the same kind of wells and the pumping/injecting wells Conclusions In the real project, the spacing of wells should be expanded in order to slow down the time of heat through; if the furnished well area is limited, we may be appropriate to increase the spacing of pumping and irrigating wells and reduce the spacing of the same kind of wells to slow down and reduce the heat through, The increasing number of pumping and irrigating wells contributes to delaying heat through time. in real engineering design, in order to save the initial investment and operating costs, the number of pumping wells may be properly increased.

The Effect of the Winding Materials on the Compression and Bending Properties of GFRP Bars Haishuang Liu1,a ,Ke Zhao2,b and Ze Liu2,c 1,2 School of Chemical Engineering and Energy, Zhengzhou University, Zhengzhou 450001, China ahaishuangliu@163.com, bkzhao2005@126.com,c1047989590@qq.com Keywords: winding materials, compression property, bending property, GFRP bars Abstract.
As this material has high tensile strength, light weight, good durability, etc, it has become a new generation of civil engineering structural material that can be used in some occasions instead of steel[1,2].
Due to the high tensible strength of GFRP bars, engineering applications is mainly to make full use of the advantage of high tensile strength of GFRP bars.
In addition to stretch effect, GFRP bars will be subjected to compression, bending, shear and other effects in the practical engineering [5,6].
