摘要
CASS5.1是基于AutoCAD 2002平台开发的数字化地形地籍成图软件,运用其丰富的DTM建模功能可完成复杂线形的重心计算,其计算方法简便、精度可靠。介绍该软件在南昌生米大桥半跨钢管拱重心计算中的应用。
The CASS5. 1 software is the digital topographic and cadastral drawing software developed on platform AutoCAD 2002. With a great variety of DTM modeling functions of the software, the gravitational center of complicated geometry can be computed. The computation method of the software is simple, precise and reliable. In this paper, the application of the software to computation of gravitational center of half a steel tube arch of the Shengmi Bridge in Nanchang is presented.
