摘  要：該文依托杭州某鄰近運(yùn)營(yíng)地鐵隧道的基樁施工工程，對(duì)鄰近樁基施工后管片錯(cuò)臺(tái)進(jìn)行分析，得到結(jié)果為施工后左右線隧道管片腰部的錯(cuò)臺(tái)量較大。鄰近樁基施工對(duì)附近錯(cuò)臺(tái)量較大的管片有抑制其繼續(xù)擴(kuò)大的趨勢(shì)，而對(duì)于錯(cuò)臺(tái)量較小或者無(wú)錯(cuò)臺(tái)的管片則會(huì)影響其發(fā)生錯(cuò)臺(tái)。

關(guān)鍵詞：運(yùn)營(yíng)隧道；隧道管片；錯(cuò)臺(tái)量；樁基施工；水平位移

Abstract： In this paper， based on the foundation pile construction project of a nearby subway tunnel in Hangzhou， the faulting of slab ends of the segment after the construction of the adjacent pile foundation is analyzed， and the results are as follows： There is a large amount of faulting of slab ends at the waist of the tunnel segment on the left and right lines after construction. The construction of adjacent pile foundation has a tendency to restrain the expansion of the segment with a large number of faults nearby， while the segment with less or no fault will affect the occurrence of the fault.

Keywords： operating tunnel; tunnel segment; number of faulting of slab endss; pile foundation construction; horizontal displacement
