Combined with the features of arch bridge,it makes a research of bridge supporting frame setting plan,discusses the force on arch section,vertical force calculation of each arch section to the supporting frame,the thrust face calculation at supporting pier and supporting frame calculation,and gets the rational horizontal and vertical supporting wood size.

Combined with the construction of Jieyang separated overpass bridge,it analyzes the keys in the construction of full space steel support,so as to improve the supporting frame construction technique of continuous box girder and guarantee the construction of bridge projects.

The design and erection scheme of scaffold in high-rise comprehensive building engineering;

Some factors such as bridge site, main span beam structure, investment and construction period make conventional steel girder erection schemes (such as launching method and single-end large cantilevered assembling construction method) impossible, so new erection schemes must be taken into consideration.

Based on concrete engineering practice,the fitting construction order,fitting method and control of 50 m precast T-beam were discussed in detail,and the credible erection scheme was provided.

The paper analyses the basic features of modern physical distribution, introduces the infrastructure and development strategy of modern physical distribution in Shanxi Province, and expounds the building plan of information platform of modern physical distribution.
