Application of ObjectARX in Soil Nailing CAD System

The process of soil nailing CAD systern based on database is illustrated, and the basic knowledge about ObjectARX is introduced. The construction drawings of soil nailing which conform to the practical custom are produced by the successful operation on graphic database. The one-dimensional Brent method and golden section are adopted to search the failure surface automatically. Not only the requirement of the computing speed is met but also the slope analysis of the construction stage is achieved.
