【摘要】：近年來,隨著軌道交通迅速、大規(guī)模的發(fā)展,越來越多的地鐵建設(shè)將面臨多次穿越既有地鐵線路的問題。根據(jù)有關(guān)研究,在2050年北京市區(qū)軌道交通線路規(guī)劃圖中,節(jié)點(diǎn)車站和地鐵區(qū)間穿越段的數(shù)目高達(dá)118處。由于盾構(gòu)下穿過程中不可避免地對(duì)既有地鐵運(yùn)營(yíng)隧道造成影響,引起沉降或隆起,地鐵運(yùn)營(yíng)對(duì)既有線的軌道變形又有非常嚴(yán)格的控制標(biāo)準(zhǔn),如北京地鐵盾構(gòu)隧道下穿既有地鐵運(yùn)營(yíng)隧道多為“特、一級(jí)風(fēng)險(xiǎn)工程”,因此通過實(shí)時(shí)監(jiān)測(cè)數(shù)據(jù)得出變形趨勢(shì)與及時(shí)調(diào)整相應(yīng)控制措施,從而對(duì)施工進(jìn)行指導(dǎo),以確保運(yùn)營(yíng)隧道的正常運(yùn)行和安全是非常有必要的。北京地鐵盾構(gòu)隧道下穿既有地鐵運(yùn)營(yíng)隧道,安全風(fēng)險(xiǎn)控制等級(jí)要求高。盾構(gòu)下穿過程中不可避免地對(duì)地鐵運(yùn)營(yíng)隧道造成影響,引起沉降或隆起,存在潛在風(fēng)險(xiǎn)。通過盾構(gòu)超近距離下穿地鐵運(yùn)營(yíng)隧道工程實(shí)例為背景,研究分析規(guī)范性的自動(dòng)化監(jiān)測(cè)數(shù)據(jù)對(duì)實(shí)時(shí)反映施工動(dòng)態(tài)的重要性,研究和探討既有地鐵區(qū)間傳統(tǒng)、新興的監(jiān)測(cè)手段及監(jiān)測(cè)方法,并結(jié)合實(shí)測(cè)數(shù)據(jù)對(duì)盾構(gòu)近距離穿越擾動(dòng)影響進(jìn)行定量分析,討論施工參數(shù)和相關(guān)控制措施研究,通過實(shí)測(cè)數(shù)據(jù)對(duì)既有線結(jié)構(gòu)變形規(guī)律和盾構(gòu)下穿既有線施工技術(shù)進(jìn)行分析研究,為越來越多的交叉穿越工程提供資料,為國(guó)內(nèi)外類似工程提供借鑒。
[Abstract]:In recent years, with the rapid development of rail transit, more and more subway construction will face the problem of crossing existing subway lines many times. According to relevant research, the number of node stations and subway crossing sections in the urban rail transit planning map of Beijing in 2050 is as high as 118. Due to the inevitable influence of shield tunneling on the existing subway tunnel and the settlement or uplift, the subway operation has a very strict control standard to the deformation of the existing railway track. For example, most of Beijing metro shield tunnel underpass the existing subway operating tunnel is "special, first-class risk engineering", so through real-time monitoring data to obtain the deformation trend and timely adjustment of the corresponding control measures, so as to guide the construction. It is necessary to ensure the normal operation and safety of the operating tunnel. Under the shield tunnel of Beijing Metro, the safety risk control level is high. In the process of shield tunneling, the subway tunnel is inevitably affected, causing settlement or uplift, and there are potential risks. Based on the example of shield tunneling project, the importance of normative automatic monitoring data to reflect the construction dynamic in real time is studied and analyzed, and the tradition of existing subway section is studied and discussed. The new monitoring means and monitoring methods, combined with the measured data, are used to quantitatively analyze the impact of shield tunneling on the close-through disturbance, and the construction parameters and related control measures are discussed. Based on the measured data, the deformation law of the existing railway structure and the construction technology of the existing railway under shield tunneling are analyzed and studied, which provides data for more and more cross crossing projects, and provides reference for similar projects at home and abroad.
