The HuangGouShan typed hotwater deposition and superimposed reformation gold deposit in Laoling mineralization belt of South Jilin Province;

On the basis of the analyses of tectonic deformation,the tectonic evolution was established by the reconstruction of basin evolution and structural superimposed reformation sequence.

Taking the reinforcement and reconstruction project of Hexi residential building of Shanxi Association for Science and Technology as the example, this paper introduces the design idea of reinforcement and reconstruction, and expounds the difficulties in and the countermeasures for the reconstruction project.

In recent years,along with reinforcement and reconstruction of RC structures to become increased,the more and more high intensity adhesives indraughted and application studied in engineering practise,which makes the technology of post-embedded bars have more and more market quotient in reinforcement and reconstruction of RC structures.

For different kinds of underground space,such as ordinary basement,metro,forepast civil air defence,old tunnel,antiquated mine,underground common ditch,the design method for their reinforcement and reconstruction and the foundation of inner function dividing are discussed.

The results show that there are some potential safety hazards in the rack, and must check the structure of the rack once again and carry out the reinforcement and transformation of the rack.

The article introduces the application of reinforcing and transforming bridges in the practical engineering through combining with reinforcement and transformation design of two bridges.

An office building of reinforcement steel frame nodal analysis;

Main items and design contents of Sanhe navigation lock reinforcement project is introduced in this paper.

Based upon the reinforcement design for the crane beam of No.
