Micro-Seismic Monitoring Technology Microseismic monitoring technology uses earthquake wave from rock deformation or rock damage to monitor the engineering rock mass stability.
Also, it is free to build into a special instrument system and has outstanding advantages in engineering applications and economic activities.
This article uses Newton iteration method and the results meet the engineering requirements.
Set the orientation software as 10-2 to meet the requirements of engineering precision and computation speed. (3) combination error and space error.

It is developed by staff of environmental monitoring research institute of America Brigham Young University and the U.S. military drainage engineering test workstations.
Oil pipeline engineering is an underground engineering which always buried underground.

Variable Rigidity Pile (Pile Partner) Deal with Unconfined Direct and Indirect Footing (Foundation) Jiangwei XUE1,2,a, Jingluo CAI1,3 , Yong YANG4 , and Xinsheng GE1 1 College of Architecture and Civil Engineering,Taiyuan University of Technology,Taiyuan, China; 2 Taiyuan Committee of Housing & Municipal and Rural Construction,Taiyuan, China; 3 North China Institute of Science and Technology, Beijing, China; 4 Shenzhen SDRE Co.
These codes above are explained in Code for design of building foundation [4] (GB 50007-2002) that the seismic fortification of high-rise building raft shape and box embedded depth of foundation should not be less than 1/15 height of the building, is based on the engineering practice and scientific research.
Although these codes above are simple for engineers, there might be Erroneous Judgement or Discrimination.

Confined-accelerated Creep Tests to Determine the Creep Reduction Factor Zhen Zhang1, Duoyi zhu, Tengfei Chen, Tao Wang 1School of Civil Engineering at Central South University,410075,Changsha Keywords: Creep, Time-Temperature Superposition Principle, Geogrids, Confined and Accelerated Creep Tests, Master Curves Abstrct: The creep characteristics of geogrids is one of the most important factors affecting its permanent in reinforced soil structures. currently, most of the creep tests are under unconfined conditions, the results deviates significantly from the real status in the application .
The creep reduction factor is mainly used in the engineering design .
According to the formula (2) ,the creep reduction factor of unconfined geogrids is: The creep reduction factor of confined geogrids is: Applications in engineering The unstable slope is located in Lingbao to Lushi Section’s No.
(6) Compared with two creep reduction factors,it is found that the creep reduction factor in unconfined condition is conservative .Applied to the engineering , take advange of the creep reduction factor in unconfined condition will make the project cost increased by 16%.The application to huge engineering will cost more.
