【提要】  通過在人工挖孔嵌巖樁樁頂、樁端及樁周各主要土層的分界面埋設(shè)鋼筋計的靜荷載試驗，分析了嵌巖樁側(cè)阻力、端阻力的變化規(guī)律。并對實測結(jié)果與勘察報告建議值以及規(guī)范計算值進行了比較，探討了巖性、嵌巖深度等對承載力的影響，提出了計算嵌巖樁承載力所需系數(shù)的取值。
【關(guān)鍵詞】  人工挖孔嵌巖樁  樁側(cè)阻力  樁端阻力
Discussion for the Bearing Capacity Selection of Rock Socketed Piles/Shi Feng1,Chen Xiaoxian1,Xu Guoping1,Wang Jiehui2(1.Fujian Building Science Research nstitute,Fuzhou 350025,China;2.Branch Courts in Fuzhou of Chongqing University Architecture Designing Institute,Fuzhou 350013,China)
Abstract:Based on the static loading tests on rock socketed piles in which the stain gauges were mounted at the top and the interfaces of soil strata,the behaviors of skin resistance and toe resistance are analyzed.The results of the test,the values suggested in the nvestigation report and calculating values are compared and the effects of rocky haracter,depth of rock socketed are discussed.The coefficients for calculating the bearing capacity of rock socketed piles are presented.
Keywords:artifical rock socketed piles;skin resistance;toe resistance
