According to the load characteristics of the main building in foundation optimization design of Genyuan Marriott Building (the tallest building in Ningxia), pile type, pile diameter, pile length and pile vertical bearing capacity of different schemes were compared. The theoretical calculation results were checked according to the off-site pile test results and the engineering pile detections results, and then reasonable pile construction drawing was made.Keywords: foundation; post-grouting pile; pile diameter; pile length; vertical bearing capacity; test pile作者簡介：崔世敏，學(xué)士，高級工程師，一級注冊結(jié)構(gòu)工程師，結(jié)構(gòu)副總工程師，Email：cuishimin@sunlay.cn。參考文獻［1］山西冶金巖土工程勘察總公司.巖土工程勘察報告(詳勘)［R］.2011.［2］JGJ 94―2008 建筑樁基技術(shù)規(guī)范［S］.北京：中國建筑工業(yè)出版社，2008.［3］GB 50007—2011 建筑地基基礎(chǔ)設(shè)計規(guī)范［S］.北京：中國建筑工業(yè)出版社，2012.［4］全國民用建筑工程設(shè)計技術(shù)措施（地基與基礎(chǔ)）［S］.2009年版.北京：中國計劃出版社，2009.［5］寧夏建筑設(shè)計研究院有限公司.試樁檢測報告［R］.2011.［6］JGJ 106—2003建筑基樁檢測技術(shù)規(guī)范 ［S］.北京:中國建筑工業(yè)出版社，2003.
