［摘要］對(duì)山區(qū)巖石地基基礎(chǔ)受剪承載力計(jì)算、較破碎巖中嵌巖樁單樁豎向承載力計(jì)算、巖質(zhì)邊坡上有建筑物的邊坡穩(wěn)定性分析這三個(gè)在貴州地基基礎(chǔ)設(shè)計(jì)中常見(jiàn)的問(wèn)題進(jìn)行探討。分析了《貴州建筑地基基礎(chǔ)設(shè)計(jì)規(guī)范》（DB 22/45—2004）和《貴州省建筑樁基設(shè)計(jì)與施工技術(shù)規(guī)程》（送審稿）中對(duì)此提出的設(shè)計(jì)方法，可供類似工程參考。

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
