混凝土耐久性DBMS的构建与应用

影响混凝土耐久性的因素是复杂的，表征耐久性状况的参数是多种多样的，一般的数据处理方法难以方便地从大量的试验数据中去伪存真，找出各数据间的内在规律。而数据库管理系统可方便有效的管理、分析处理繁杂的数据，从而为混凝土耐久性评估、预测提供一个有力的工具。文章对面向对象语言VB6．0数据库编程的特点和耐久性的影响因素进行了介绍，并详尽阐述了耐久性数据库管理系统(DurDBMS)的数据库结构和功能设计。最后采用建立的系统对混凝土碳化问题进行了处理．结果显示预测误差符合精度要求、影响因素的定量分析与定性分析吻合性好。

Construction and Application of DBMS About Concrete Durability

Factors affecting concrete durability are various and complex. And the number of parameters that characterize the status of durability is large. It's not easy to eliminate error from numerous data and find out the internal law among them. However, it's convenient for one database management system to manage and dispose of data so as to evaluate and forecast concrete durability. This paper briefly discusses the virtues of the object-oriented programming-VB6.0 for database and factors resulting in damage of concrete durability, introduces carefully the structure and function of DurDBMS. At the end of the paper, an instance is set up to transact carbonate and the result reveals that the error of prediction meets with request of experiment, quantitative analysis accords with that of qualitative.
