According to these facts, this thesis aimes at this kind of requirement of the highway construction, carries on the detailed research to the retaining wall drawing system, and make use of the VC++ 6.0 and ObjectARX 2000 SDK, based the Accees database, developes the retaining wall drawing system based on ARX(AutoCAD Runtime eXtension) ( DTQ2005) in AutoCAD 2000/2002 environments.
Based on the known theoretical research at home and abroad, common theories of earth pressure and their adaptabilities are discussed in this paper, and emphases are put on the methods of earth pressure calculation and checking of strength and stability for retaining walls with balancing platform, especially under the condition of cohesive filling soil and over loading.
Follow both that of text summarize reinforced earth breast wall collapse mode and stability require, the design and calculation method of the introduce adoptive constitutive model research reinforced earth retaining wall.
Soil nailed wall and form anchor breast wall have their respective principles and characteristics, although similar inform, they have different methods of construction and different application situation.
The paper analyse advantage and defect of earth-work strip,steel strip and rein foucmenf Concrere tie bar strip,and expound a foreground to implement factory and standard in the construction of reinforced earth breast wall,by the application of CAT steel and plastic complex tie bar strip in the construction of YingKou interchange.
