摘　　要：本文应用分数维实用计算模型,通过线状地质对象"西安典型地裂缝"、"渭河西安段"及"长安—临潼断裂西安段"分数维计算及其特征分析,得出上述三类线状地质对象分数维一般特征及规律,既为其空间分布几何特征描述提供量化参考指标,也为地裂缝成因机理深入探索提供空间线索。Applying practical calculation model of fractal dimension,through fractal dimension calculation and characteristic analysis to the linear geological objects ＂Xi＇an typically ground fissures＂,＂Weihe River Xi＇an Segment＂ and ＂Chang＇an-Lintong fault Xian Segment＂,we have derived the general characteristics and rules of fractal dimension from the above-mentioned linear geological objects,which provided a quantitative reference indicator to describe their spatial distribution and geometrical features,as well as the spatial clues to depth explore the ground fissures formation mechanism.
