结合某一土方工程的实例详细阐述了如何利用等高线在组建特殊地貌土方计算数据库的应用。利用等高线可以快速地生成大量的高程数据库的特点,加密了某一特定地貌(如虾池、鱼塘等)的高程,使得土方量概算值更加接近于实际值;其计算精度得到保证,又提高了工作效率。 更多还原

【Abstract】 Combined with a detailed example of earthworks,it described how to use the contour in the formation of special landscape earthwork calculation database applications.The method exploited the contour could quickly generate a lot of elevation characteristics of the database to encrypt a particular landscape(such as shrimp ponds,fish ponds,etc.) of elevation,making the value of earthwork estimates closer to actual value,assuring earth-moving calculation accuracy and improving efficiency. 更多还原
