Bridge strengthening technology is a new hot spot of bridge engineering now, and choice for a scientific strengthening scheme is an important presupposition to ensure the effectiveness and quality of a project.
It is includes the following aspects: the reinforcing scheme is advanced technology; the selected scheme tested by rich engineering practice, the technology is proved mature; the selected reinforcing scheme is adapted to reasons of structure reinforcements; the selected reinforcing scheme is adapted to the environments conditions of structure as well
Conclusions The bridge reinforcement is the bridge to the development of new hot spot, the rational choice of reinforcing scheme is to guarantee the quality and effectiveness of engineering of the important premise.

Tensegrity structures are of interest to architecture and engineering as a practical means to explore lightweight and rapidly deployable modular structures that have a high degree of geometric freedom and formal potency.
Initially conceived as a novel approach to structures for the purpose of art, research into tensegrity and its applications in architecture and engineering has a long history.
Tensegrity is of interest in architecture and engineering as it enables the generation of lightweight and rapidly deployable modular structures that have a high degree of geometric freedom.
A concept model of the bridge was fabricated to test the overall behaviour of the structure and ensure that the module fulfilled its engineering and design requirements.

Theoretical study on vertical earth pressure calculation for positive-busied culverts under high embank Fan He1, a, Wang Ying1,b and Ning Bao-kuan 1,c 1School of Architecture and Civil Engineering, Shenyang University of Technology, Shenyang, P.R.China, 110870.
High embank culverts have been widely used in railway, highway, municipal works, and other underground engineering.
Introduction Culvert is highway engineering structure as laid across embankment and buried below fill.
Calculation Theory Introduction Representative and more engineering applied theories are Marston theory, Zeng guo-xi theory, and Gu an-quan theory.
The formula is realistic meaning to high embank culvert engineering design.

Some advantages of this new method are briefly introduced, compared with the shallow mining methods for underground engineering construction, as well as its application in subway engineering.
According to further study, this new construction method will be widely used in underground engineering projects.
The CRD method is one of shallow mining methods for underground engineering construction.
The PBA method is regarded as one of shallow mining methods for underground engineering construction.
