［摘要］我國(guó)的城市軌道交通建設(shè)日趨成熟，已有大量實(shí)例證實(shí)，軌道交通的修建和運(yùn)行會(huì)對(duì)周邊建筑產(chǎn)生影響。選取西安地鐵二號(hào)線及其沿線重要文物建筑——西安城墻南、北門和鐘樓為研究對(duì)象，采用數(shù)值模擬與現(xiàn)場(chǎng)實(shí)測(cè)相結(jié)合的方法，從文物建筑安全保護(hù)方面系統(tǒng)研究地鐵盾構(gòu)施工和運(yùn)營(yíng)振動(dòng)對(duì)城墻和鐘樓的影響。研究結(jié)果表明，城墻和鐘樓的變形量在控制范圍內(nèi)。研究成果可為地鐵建設(shè)中文物保護(hù)方案提供科學(xué)依據(jù)。［關(guān)鍵詞］西安地鐵; 盾構(gòu)施工; 地面沉降; 運(yùn)營(yíng)振動(dòng); 文物建筑中圖分類號(hào)：TU311, TB533 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)19-0087-05
Influence study on subway construction and operation vibration on cultural relics buildingsQian Chunyu1, Li Junlian1, Zhang Wei1, Zheng Jianguo1, Kang Zuo2, Gao Shuxiao1（1 China JIKAN Research Institute of Engineering Investigations and Design, Co., Ltd., Xi'an 710043, China; 2 Xi'an City Underground Railway Limited Liability Company, Xi'an 710018, China)Abstract: The construction of urban rail transit in our country is becoming more and more mature, and there are many examples to prove that the construction and operation of rail transportation have impacts on the surrounding buildings. Xi'an Subway Line 2 was selected as the research object as well as important cultural relics buildings along the line including the south gate, north gate and the bell tower of Xi'an city wall. Using the combined method of numerical simulation and field measurement, the influences of subway shield tunnel construction and operation vibration on the walls and bell tower were systematically studied from the perspective of cultural relics building security protection. The research results show that the deformations of the walls and the bell tower are in the control range. The research results can provide scientific basis for the cultural relics protection scheme in subway construction.Keywords: Xi'an subway; shield construction; ground settlement; operation vibration; cultural relics building
