淤地坝CAD系统的开发应用

淤地坝是黄丘区治理水土流失的主要骨干工程措施之一,也是发展山丘区粮食生产的有效途径。为了变革淤地坝的传统设计方法,提高设计精度和速度,缩减淤地坝建设投资,作者经过近两年的研究,开发出一套淤地坝计算机辅助设计系统——淤地坝CAD。该系统具有较强的数值计算、数据处理、优化设计和辅助绘图功能。应用实践表明,淤地坝CAD系统可以提高设计工效3～6倍,节约工程投资5％～10％。

Exploitation of CAD System for Design of Check Dams

Check dam is one of the key projects for harnessing the soil loss in rollied-hilly loess area, and also an effective way in developing the agricultural production. Through about two years' study, the authors exploited a computor aided design system for check dam(CDCAD). This system had powerful functions of numerical calculation ,data processing, optimum design and auxiliary mapping. Practical application indicated that the CAD system ecould raise efficiency of design three to six times, and save the cost of projects by 5percent to 10 percent.
