付波,黃志廣(江西省建筑設(shè)計研究總院,南昌 330046)[摘要]介紹了南昌地區(qū)某高層住宅基礎(chǔ)采用全夯樁替代嵌巖樁的設(shè)計過程。與傳統(tǒng)嵌巖樁相比,全夯樁具有施工工藝簡單、施工速度快及工程造價低等優(yōu)點。并對全夯樁進行了樁基檢測及沉降觀測,結(jié)果表明其樁身質(zhì)量、樁基承載力及樁基沉降均滿足規(guī)范要求,從而驗證了全夯樁作為高層住宅基礎(chǔ)的安全可靠性和經(jīng)濟合理性,拓寬了全夯樁在高層建筑基礎(chǔ)中的應(yīng)用范圍。[關(guān)鍵詞]全夯樁;高層建筑;基礎(chǔ)應(yīng)用中圖分類號:TU473.14 文獻標識碼:A 文章編號:1002-848X(2013)01-0100-03Application of all-course ram-compaction pile in the high-rise building foundationFu Bo, Huang Zhiguang(Jiangxi Province Architectural Design & Research Institute, Nanchang 330046, China)Abstract: The design of a high-rise residential foundation in Nanchang was introduced and all-course ram-compaction pile was used instead of rock-socketed pile. Compared with the traditional rocksocketed pile, all-course ram-compaction pile has some advantages such as simple construction process, fast construction speed and low construction cost. The results of pile testing and settlement observation can meet the requirements of specification in pile quality, pile bearing capacity and pile settlement. So the all-course ram-compaction pile used in the high-rise residential foundation is proved to be feasible in safe reliability and economy rationality. The all-course ram-compaction pile can be further applied in the high-rise building foundation.Keywords: all-course ram-compaction pile; high-rise building; foundation application作者簡介:付波,一級注冊結(jié)構(gòu)工程師,高級工程師,Email: fubowelcome@163.com參考文獻[1]席寧中,劉金礪,張春生. 擴底樁的側(cè)阻松弛削弱效應(yīng)[J]. 土木工程學(xué)報,2007,40(S1): 179-183.
