中美土质分类标准模型转换程序设计

Design of Model Conversion Program Based on Chinese and American Soil Classification Standards

目前,国际上已形成以美国(USCS)为依据的土质统一分类标准(ASTM),与中国规范分类标准不同。因此,开展中美土质分类标准研究,提出建立中美土质分类指标转换数据模型,采用二叉树遍历算法实现中国规范与ASTM土质分类标准模型之间转换,能够有效突破中美岩土工程土质分类标准差异所形成的障碍。程序集成了信息配置、导入接口、计算、转换、导出接口等5大模块,用户通过操作友好的人-机交互界面,既适应我国国情使用习惯,又符合中美二国土的工程分类标准要求,所用方法对中国企业开拓海外市场具有参考价值。

At present, a unified soil classification standard by ASTM based on USCS has been well known in the world, which is different from Chinese standard. Therefore, it is necessary to study Chinese and American soil classification standards, build a data model for the conversion between Chinese and American soil classification indices, and achieve the successful conversion between Chinese and ASTM soil classification model by using binary tree traversal algorithm. The above work can effectively eliminate the obstacles caused by the difference between Chinese and American standards on the geotechnical engineering soil classification. The model conversion program integrates five modules, i.e. information configuration, leading-in interface, calculation, conversion and leading-out interface. Users apply operation-friendly man-machine interface, which accords with not only the habit of Chinese customers, but also the soil classification requirements of the above two countries. The design method serves as a reference for Chinese enterprises developing the markets overseas.
