摘要
阐述基于数据库的土钉支护的设计过程。介绍ObjectARX基础知识,并将其应用于土钉支护CAD系统中,成功地对AutoCAD底层数据库进行操作,实现了符合实际工程习惯的土钉支护施工图的绘制。在破坏面的自动搜索上,采取黄金分割法与一维Brent法相结合的方法,很好地实现了自动搜索功能。这一方法不但很好地满足了计算速度的要求,而且也实现了考虑施工阶段边坡分析的目标。
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.
