［摘要］对山区岩石地基基础受剪承载力计算、较破碎岩中嵌岩桩单桩竖向承载力计算、岩质边坡上有建筑物的边坡稳定性分析这三个在贵州地基基础设计中常见的问题进行探讨。分析了《贵州建筑地基基础设计规范》（DB 22/45—2004）和《贵州省建筑桩基设计与施工技术规程》（送审稿）中对此提出的设计方法，可供类似工程参考。

Abstract:The three commonly design problems for footings on rock foundation in mountain area，including the calculation on shear bearing capacity for single column footings on rock foundation，the calculation on vertical bearing capacity of less cracked rock-socketed pile，stability analysis of slope for construction on rock slope were discussed. The design methods which were suggested in Code for design of building foundation of Guizhou(DB 22/45—2004) and Technical specification for building pile foundation in Guizhou Province were analyzed, which provide a reference for the  similar projects.

Keywords:rock foundation； single column footing； shear bearing capacity； less cracked rock； rock-socketed pile； rock slope；  stability analysis
