Taking cable dome of Coal Trading Center of China as an example, the constitution of monitoring system and the methods and contents of the monitoring were presented in detail. The analysis of the monitoring data of the stress, displacement and cable force shows that the structure was correspond with the design so that it could be put into use.Keywords:cable dome; construction monitoring; stress; displacement; cable force*北京市博士后工作經(jīng)費(fèi)資助項(xiàng)目(2012ZZ\|107), 北京市科技新星計(jì)劃(Z121106002512099)。作者簡(jiǎn)介:劉占省,博士,Email:lzs4216@163.com。參考文獻(xiàn)[1]徐瑞龍, 雷俊方, 沈斌,等. 虹橋機(jī)場(chǎng)二期屋蓋張弦結(jié)構(gòu)內(nèi)力和溫度監(jiān)測(cè)[J]. 建筑結(jié)構(gòu), 2012, 42(10):8386.[2]吳金志,柳明亮, 沈斌,等. 張弦桁架下弦拉索振動(dòng)頻率測(cè)試及理論模型研究[J]. 建筑結(jié)構(gòu), 2012,42(10): 7982.[3]劉占省,陳志華. 茌平體育館健康監(jiān)測(cè)方案設(shè)計(jì)研究[C]//第三屆全國鋼結(jié)構(gòu)工程技術(shù)交流會(huì)論文集. 2010.[4]秦杰, 王澤強(qiáng), 張然,等. 2008奧運(yùn)會(huì)羽毛球館預(yù)應(yīng)力施工監(jiān)測(cè)研究[J]. 建筑結(jié)構(gòu)學(xué)報(bào), 2007, 28(6): 8391.[5]胡正平, 李婷, 趙楠, 等. 中國(太原)煤炭交易中心:展覽中心結(jié)構(gòu)設(shè)計(jì)[J]. 建筑結(jié)構(gòu),2011,41(9):1621.
