(青島騰遠設計事務所有限公司,青島 266100)[摘要]針對不同規(guī)范、規(guī)程、技術措施的抗浮錨桿計算公式不統(tǒng)一的現(xiàn)狀,對抗浮水位的取值、水浮力設計值的分項系數(shù)取值、單根錨桿抗拔力的計算、鋼筋是否可分批截斷等提出了合理的建議。采用SAP2000軟件中Hook單元模擬抗浮錨桿并進行計算,分析了錨桿的布置方式、底板厚度、上部壓重、基床系數(shù)、基礎梁、底板外挑等因素對錨桿拉力的影響,對錨桿的合理設計提出了有益的建議。[關鍵詞]抗浮錨桿; 設計水位; 抗拔力; 合理布置中圖分類號:TU943 文獻標識碼:A 文章編號:1002-848X(2013)22-0080-06Research on rational design of anti-floating anchorSun Shaodong, Hu Haitao, Jing Yanqing, Li Huating(Qingdao Tengyuan Design Institute Co., Ltd., Qingdao 266100, China )Abstract: Based on the current situation that there is no unified calculating formula of anti-floating anchor in terms of different codes, specifications and technical measures, rational suggestions were put forward on calculation of anti-floating water level value, partial coefficient value of water buoyancy design value, calculation of single anchor pullout force, and whether rebars can be partially cut off. With application of Hook element of SAP2000 software to simulate the anti-floating anchor calculation, influence of factors such as anchor layouts, plate thickness, upper pressure, coefficient of subgrade, foundation beam and external plate on anchor pull were analyzed. Some useful suggestions on reasonable design of anchor were presented as well.Keywords: anti-floating anchor; design water level; pullout force; rational layout作者簡介:孫紹東,碩士,高級工程師,一級注冊結構工程師,Email:69610987@163.com。參考文獻[1]李華亭,張冬云.巖石地基中高層建筑地下室的設計[C]//第十七屆全國高層建筑結構學術會議論文集.杭州,2002:657-662.[2]GB 50069—2002給排水工程構筑物結構設計規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2003.[3]JTG D60—2004公路橋涵設計通用規(guī)范[S].北京:人民交通出版社,2004.[4]GB 50330—2002建筑邊坡工程技術規(guī)范[S]. 北京:中國建筑工業(yè)出版社,2002.[5]全國民用建筑技術措施(地基與基礎)[M]. 2009年版.北京:中國計劃出版社,2010.[6]CECS 22:2005巖土錨桿(索)技術規(guī)程 [S]. 北京:中國計劃出版社,2005.[7]東南大學,天津大學,同濟大學.混凝土結構(上冊)[M]. 北京:中國建筑工業(yè)出版社,2001.[8]GB 50007—2011建筑地基基礎設計規(guī)范[S].北京:中國建筑工業(yè)出版社,2012.[9]程良奎,范景倫,韓軍. 巖土錨固[M].北京:中國建筑工業(yè)出版社,2003.
