<正>为了解决二灰碎石半刚性基层材料在道路运营阶段易出现干缩和温缩而产生裂缝的现象，利用钢渣具有和天然石料一样的强度以及微膨胀性的特点，用钢渣取代部分粉煤灰。研究了掺钢渣后的二灰碎石干燥收缩的变化情况。结果表明：当钢渣掺量适宜时（m钢渣：m粉煤灰=1：2），二灰碎石的干缩性能能得到较好的改善。

This paper took Jiangxi province which has typical red soil resources in China as a case using the data of the second country general detailed soil survey, with the ARC/INFO software, MapObjects and VB supporting, to establish the red soil resources information system of small scale (1, 1 000 000). This interface was fulfilled with the support of MapObjects. The soil information system manages the attribute data and spatial data uniformly, and establishes the contact between them. This system provides querying function, such as from map to table, from table to map and from table to table, and the function of outputting thematic map.
