Research on Calculation of Equivalent Damping Ratio of Electrical Transmission Tower-Line System with Viscoelastic Dampers Cong Zeng a, Dongxue Hao b, Liqun Hou c Institute of Architectural Engineering, Northeast Dianli University, Jilin 132012,China a zc_1113@126.com, b haodongxue2005@126.com, c hlq_work@sina.com Keywords: Viscoelastic damper, Additional equivalent damping ratio, Electrical transmission tower-line system Abstract: Installing viscoelastic dampers on electrical transmission tower will significantly reduce the wind-induced vibration response of electrical transmission tower-line system.
The control of transmission tower vibration has become an important research topic in civil engineering.
Through a practical engineering project, the responses with viscous damper model and the one with additional damping ratio model were compared under earth quake time-hi-story, which verified that the results of the method of calculation for equivalent damping ratio satisfy the engineering precision[3].

Combining characteristics of pipe-jacking tunnel, this paper analyzed key-points of construction technology and engineering troubles which occurrence possibly in construction, and introduced some treatment measures.
Features of pipe jacking tunnel project Compared with ordinary civil engineering project, the pipe jacking tunnel has its own features as follows: The equipments are appropriative and the project is relying on the equipment.
So the risk of pipe jacking tunneling is higher than ordinary civil engineering project and demands the technicians to have the merits of being good at sum-up, mastering advanced technology and predicting possible troubles to avoid accidents and risks.

Research on the Formula of the Height of Bearing Push-extend Under-reamed of the Push-extend Multi-under-reamed Pile Yongmei Qian1,a , Xiaolong liu1,b and Ruozhu Wang1,c 1Jilin Institute of Architecture and Civil Engineering, Changchun, China, a654675316@qq.com, bliuxiaolong@163.com, c wangruozhu@126.com Keywords: the Push-extend Multi-under-reamed Concrete Pile, failure principle, theory of shear resistance, the height of bearing push-extend reamed Abstract.
As there is no definite calculation formula of the height of bearing push-extend reamed of the Push-extend Multi-under-reamed Concrete Pile at present, in the paper, according to the theoretical analysis and the experimental achievements on the failure principle of the soil of the Push-extend Multi-under-reamed Concrete Pile, it is made that using the theory of shear resistance to carry on the analysis, deduce the check formula of the height of bearing push-extend reamed of the Push-extend Multi-under-reamed Concrete Pile, and it is put forward that the reliable theoretical basis of the Push-extend Multi-under-reamed Concrete Pour Pile foundation design for practical engineering.
Conclusion According to theory of shear resistance, it must make punching force caused by reaction of subsoil outside punching section no more than punching ability of concrete at punching section, then it can be ensured that the bearing push-extend reamed itself do not produce punch failure, according to this it can be derived that the check formula which ensure the height of the bearing push-extend reamed, it means the height of the bearing push-extend reamed h should meet the formula as follow: For the bearing push-extend reamed are single slope, For the bearing push-extend reamed are single slope, In short, through the study of this paper, it is determined that the check formula of the height of bearing push-extend reamed and improves research results of the design of the bearing of the Push-extend Multi-under-reamed Pile, and it is put forward that the theoretical basis of engineering practice of the Push-extend Multi-under-reamed Concrete Pour Pile Acknowledgments
