Fossils are well preserved. 2. The results of comparative analysis of South China Karst Nominated Sites (Phase 1) with similar sites: among the stone forests all over the world, Shilin Stone Forest in Yunnan is neither the tallest nor the oldest one, but the most complicated in the evolution history and richest in the forms. It represented a unique evolvement mechanism of stone forest development; Libo cone karst, possesses not only the most typical karst cones, but also the most complex assemblages of the cone karst.

At first, this paper conducts in depth research on classification method, compaction propeties, granulometric composition and crushing of stone. On the basis of clarifying engineering characteristics of material of rock-filling embankment, requirements of ground treatment have been put forword in this paper. Then combined with the site test and engineering practice in SHUINAN Road and LANLIN Road, through the synthetical analysis of factors of influencing densification effect for the maximum grain size of filling material, lay-down thickness, granulometric composition, densification machinery and densification frequency etc., this paper studies key technical problems about construction technologies for spreading and leveling of filling material, choosing densification machinery, densification technology and slope construction systematically. Finally, construction technologies of filling lime-stone and sand-stone roadbed have been proposed in this paper ,which are significant for quality guarantee of highway engineering.
