An equivalent far-field dynamic-artificial-boundary condition and its accuracy studies Yi Wu School of Civil Engineering and Architecture, Southwest University of Science and Technology, Mianyang, 621010, Sichuan, China wqqem@163.com Key words: dynamic, interaction, artificial boundary, viscous, viscous-elastic, far-field Abstract. in order to eliminate some problems of ordinary artificial boundary conditions in soil-structure dynamic interaction analysis at present, such as plenty amount of work required in establishing viscous boundary and viscous-elastic boundary and the expensive computing hours cost in traditional far-field artificial boundary condition, an equivalent far-field artificial boundary condition for dynamic analysis was proposed based on the wave propagating theory and the reflection and transmission principle of wave on the interface of medium by setting a fully-transmitting layer and lower the speed of wave considerably propagating within it.
The equivalent far-field boundary proposed can be applied to engineering dynamic field such as anti-seismic of structures, vibration and impact etc.

Combined with engineering realization, an adjustment is made to the algorithm.
In Civil, including signal confirmation, interference identification, monitoring signals, spectrum management [1].
System structure and the adjusted feature parameters combined with actual engineering are introduced in detail, recognition success rate of this algorithm ratio are analyzed under different signal-to-noise (SNR), and engineering test results is presented.
Therefore, the recognition algorithm when the SNR is larger than 12 dB has good engineering practice.
Combined with engineering, the feature parameters are improved.

Experiment and Analysis on influence of moisture content on the mechanical characteristics of residual soil of granite HU Hua1, a, ZHENG Xiaoxu1,b 1Department of civil engineering of Xiamen University, Fujian Xiamen, china,361005 axmhuh@xmu.edu.cn, b408445251@qq.com Keywords: granite residual soil; moisture content; unconfined compression strength; shear strength Abstract.
In south China, residual soil is widely distributed and one of the most main soil in engineering construction at the coastal areas.
While it’s mechanical characteristics are easily affected by moisture content, which is a serious threat to engineering stability and safety.
As the result is analyzed, it shows that mechanical properties such as stress-strain relationship, unconfined compression strength, internal cohesive force, internal friction angle, and shear strength, are better than other specimens when the moisture content is 23%, which will be beneficial to the stability and security of engineering soil.

Study on methods for deep foundation pit supporting in Beijing Wenhui Tan1, Congcong Li1 and Hongbao Sun1 School of Civil and Environmental Engineering, University of Science and Technology Beijing, Beijing 100083, P.
Introduction With the development of the utilization of underground space in cities, the foundation engineering assume the feature of large-scale and deep excavation.
Deep foundation pit that has more influential elements, higher danger coefficient and more dangerous while an accident happens is a more complicated system engineering compared with a shallow one.
While the depth of foundation pit of substation is about 14m which the wall is less than 8m away from external wall of structure of this engineering, and it's prestressed anchors may has already dipped in the pit, and the west side of this engineering is Huajia district and Huajia primary school which has two basements with the depth of 6m.

A new type of complex reinforcement method for steel structure seldom used in pratical engineering mainly due to lack of theoretic and experimental support.
The results may provided reference for practical engineering.
But it will be best to make CFRP prestressed before pasting in engineering to can make full use of the advantage of high strength of CFRP.
